  1. Instructor demonstrates the inspection, donning, and doff sequence for each PPE category required in wind work—hard hat, safety glasses, hearing protection, gloves, steel-toed footwear, high-visibility vest, and fall-protection harness—while students complete a guided observation checklist noting pass/fail criteria for each item.
  2. Students pair up at a dedicated LOTO training station (simulated electrical panel, pneumatic valve, and hydraulic circuit) and take turns serving as authorized employee and affected employee, each applying padlocks and tags following a written LOTO procedure form, with the partner verifying each step.
  3. Groups of three review three scenario cards describing different energy sources found in a wind turbine (electrical, hydraulic, pneumatic, gravitational stored in blade pitch) and write out the energy-isolation steps for each, then present their procedure to the class for critique.
Full PPE kit per student (harness, hard hat, safety glasses, hearing protection, gloves, hi-vis vest, steel-toed boots), LOTO training station, padlocks and hasp set, lockout tags, blank LOTO procedure forms, OSHA LOTO topic reference handoutInstructor uses a 20-point PPE donning checklist; students must pass all safety-critical items (harness fit, hard-hat suspension, eye protection seal) with zero critical errors. LOTO practical: student completes full sequence on training station with no unprompted prompts from instructor; any skipped step is an automatic retry; pass requires two consecutive error-free runs.
3First Aid, CPR, and Wind-Site Emergency Response16labStudents demonstrate adult CPR/AED use and first-aid responses to bleeding, shock, musculoskeletal injury, and altitude-related emergencies to the performance standard required for accredited first aid/CPR certification.
  1. Accredited first aid/CPR instructor leads hands-on skills stations covering adult CPR with AED, rescue breathing, severe bleeding control with direct pressure and tourniquet application, and recognition of shock; each student performs each skill on a manikin or training device until the instructor signs off on technique.
  2. Students work through a wind-site mass-casualty scenario tabletop exercise in which a technician has fallen inside a tower and a second worker has a laceration: groups assign roles (first responder, communications, equipment retrieval), document their emergency action sequence on a written form, and debrief with the instructor.
  3. Students review the emergency action plan (EAP) format required at wind project sites, then draft a one-page EAP for a hypothetical three-turbine site that includes communication tree, nearest hospital route, helicopter landing zone designation, and confined-space rescue notification steps.

Instructor works through 15 annotated example problems drawn directly from wind-turbine tasks—converting torque from foot-pounds to newton-meters, calculating gear ratios, expressing blade pitch angles as percentages of full travel—while students annotate each step in their math notebooks using a structured note-taking template.
  2. Students work individually on a 30-problem practice set covering all lesson topics, self-grade using the provided answer key with worked solutions, identify their error types on an error-analysis form, and complete targeted re-practice problems for each error category.
  3. Small groups receive a set of real torque specification tables and a simulated work order requiring them to convert specified values to the units their wrench reads, calculate the correct number of bolt passes at each torque stage, and record results on a completed maintenance log form.
Scientific calculators (one per student), wind-turbine torque specification table excerpts, metric/US unit conversion reference card, math notebook, 30-problem practice set with worked-solution key, maintenance log forms, NCCER Core math module reference30-problem practice set scored by student using answer key; students scoring below 80% must complete the targeted re-practice set and resubmit before progressing. Torque conversion group task graded by instructor for correct values on every line of the maintenance log—any safety-critical torque error requires group to redo that section.
5Trade Math: Geometry, Trigonometry, and Electrical Formulas20theoryStudents apply right-triangle trigonometry to tower and blade geometry problems and correctly transpose and solve Ohm's Law, power, and basic three-phase electrical formulas relevant to wind turbine diagnostics.
  1. Instructor demonstrates how sine, cosine, and tangent relate to real wind-tech measurements—finding the horizontal distance from a tower base when a service vehicle must park clear of a fall zone, calculating the arc length swept by a blade—and students solve six guided problems with instructor circulation and immediate correction.
  2. Students use a scientific calculator to complete a 20-problem set covering right-triangle problems, Ohm's Law transpositions (solving for voltage, current, and resistance), and power formula variations, recording each step in a two-column format (formula setup | arithmetic) to make error-checking possible.
  3. Pairs receive a simplified single-line electrical diagram of a wind turbine's low-voltage circuit and a set of measured values; they calculate the expected current at three points, compare to the diagram's rated values, and flag any calculated deviation greater than 10% as a potential fault—documenting findings on a defect report form.
Scientific calculators, right-triangle formula reference sheet, Ohm's Law and power formula reference card, simplified wind-turbine single-line electrical diagram, 20-problem practice set with answer key, defect report forms20-problem set scored by instructor; 80% minimum to proceed. Electrical diagram task: instructor checks defect report for correct calculations at all three points and appropriate flagging of deviations—an incorrect flag on a safety-relevant overcurrent condition requires immediate re-instruction and a second attempt.
6Technical Reading, Documentation, and Digital Tools32practiceStudents accurately interpret safety data sheets, equipment operation manuals, torque and lubrication specification tables, and basic P&ID symbols, and correctly enter work-order data into a CMMS training interface.
  1. Instructor guides students through a structured reading of a real wind-turbine gearbox lubrication manual section: students highlight the hazard statements, locate the correct lubricant specification for two temperature ranges, record the change interval, and answer a 10-question comprehension quiz—then repeat the process with an SDS for the same lubricant to cross-reference PPE and spill-response requirements.
  2. Students work individually at computers to enter a completed paper inspection checklist into the school's CMMS training environment (such as a demo instance of a widely used maintenance platform), creating a corrective work order for each deficiency found, assigning priority, and attaching a photo taken with a tablet—instructor circulates and corrects data-entry errors in real time.
  3. In groups of three, students receive a one-page excerpt from a turbine hydraulic P&ID, identify and label ten specified symbols using a standard P&ID symbol reference guide, then write a three-sentence plain-language summary of what the depicted circuit does, suitable for briefing a non-technical site visitor.

CMMS data-entry task: instructor checklist verifies all required fields populated, correct priority assigned, and photo attached—any missing safety-critical field (hazard classification, corrective action) requires immediate correction. P&ID labeling: 8 of 10 symbols correctly identified to pass.
7Career Readiness, Professional Communication, and Industry Pathways28practiceStudents produce a professional resume and credential portfolio specific to wind turbine technician employment and demonstrate effective written and verbal communication in a simulated workplace scenario.
  1. Students draft a wind-tech-targeted resume using a provided template that includes a skills section mapped to NCCER and GWO credential areas, a work-history section with action-verb sentence starters, and a certifications block; peers exchange drafts and apply a resume critique rubric, then each student revises based on peer feedback before submitting a final version to the instructor.
  2. Instructor presents a panel overview of wind-industry career pathways including apprenticeship programs, NCCER Registry advancement levels, union and non-union employment models, and expected wage progression based on publicly available Department of Labor occupational data; students complete a structured note guide and then research one specific employer or apprenticeship program and present a two-minute verbal summary to the class.
  3. Students participate in a simulated morning tailgate safety meeting: one student acts as lead technician, reads a work plan aloud, identifies the day's hazards, assigns PPE, and fields questions from three classmates playing crew members who raise realistic concerns; instructor scores the lead on a professional communication rubric covering clarity, active listening, and correct safety information.
Resume template specific to wind tech trades, peer critique rubric, Bureau of Labor Statistics Occupational Outlook Handbook (wind turbine technician entry), NCCER Registry reference handout, GWO credential overview one-pager, tailgate safety meeting scenario script, professional communication scoring rubricResume: instructor rubric requires a complete certifications block, at least three trade-specific skills entries, and zero factual errors in credential names or dates—any factual error must be corrected before portfolio submission. Tailgate meeting communication rubric: student must score Meets Standard or above on clarity and correct safety information to pass; a single incorrect safety statement (wrong PPE, wrong hazard control) requires a second attempt.

4Damage Inspection Methods and Damage Classification18labStudents will inspect a set of pre-damaged composite panels and a decommissioned blade section using visual inspection, coin-tap test, and borescope, then classify each defect by type and severity using a four-level damage-category matrix.
  1. Tap-test grid: students use a coin and a dedicated tap-test hammer on flat panels containing artificially seeded delaminations of known size; they grid-mark the panel at 50 mm intervals, map sound vs. dull areas, and compare their map to the ground-truth delamination outline provided by the instructor.
  2. Borescope inspection: students thread a video borescope through a drilled access port into a hollow blade-section model to locate an internal disbond, photograph it, and record GPS coordinates (blade station, chord position) on a damage-assessment form.
  3. Damage classification exercise: students review ten color photograph sets of blade defects and assign each to a damage category (cosmetic, structural surface, structural through, or beyond field repair) using a manufacturer-style decision tree; instructor reviews answers as a group.
Pre-damaged fiberglass panel set, decommissioned blade section or training mock, coin and tap-test hammer, video borescope with tablet display, damage-assessment forms, ruler and depth gauge, photograph packet, damage-classification decision-tree referenceCompleted damage-assessment forms for three panels: student must correctly classify defect type and severity category on at least 8 of 10 photo cases (80%) AND produce a tap-test map with delamination boundary within 25 mm of actual boundary on the seeded panel.
5Resin Systems: Mixing, Pot Life, and Cure Monitoring16labStudents will mix a two-part epoxy and a two-part polyester resin to the manufacturer's specified mix ratio by weight, monitor gel time using a wooden stick test, and record ambient temperature and humidity data to predict and verify cure behavior.
  1. Ratio mixing drill: students use a digital postal scale to mix five successive batches of epoxy resin (small quantities, 50–100 g per batch) at manufacturer-specified ratio, recording actual ratio achieved; any batch outside ±2% of target ratio is remixed under instructor guidance.
  2. Pot-life experiment: students mix same-size batches at two different ambient temperatures (simulate with water bath at approximately 65 °F and 85 °F), insert wooden stir sticks at one-minute intervals, and plot gel time vs. temperature on a graph, comparing to the manufacturer's technical data sheet curve.
  3. Cure monitoring: students cast a small test plaque, record initial weight, check at four-hour intervals with a Shore D durometer, and document findings in a cure log; they predict when full post-cure hardness will be reached based on TDS data.
Two-part epoxy resin system with TDS, two-part polyester resin system with TDS, digital postal scale (0.1 g resolution), mixing cups and sticks, thermometer, hygrometer, Shore D durometer, graphing paper or tablet spreadsheet, cure log template, water bath containersInstructor checks three scored items: mix-ratio accuracy (all five batches within ±2% = pass), completed pot-life graph with at least four data points at each temperature (complete = pass), cure log with all entries and correct prediction within one cure cycle = pass; all three must pass.
6Surface Preparation: Grinding, Scarfing, and Solvent Wipe18labStudents will prepare a damaged composite panel for structural repair by grinding a scarf bevel at the correct angle, cleaning with solvent per the repair manual, and achieving a surface profile verified by feeler gauge that meets the specified scarf ratio.
  1. Grinding demonstration: instructor demonstrates angle-grinder setup, body position relative to the work surface, progression from coarse to fine grit, and measurement of scarf angle using a protractor; students observe and take written notes.
  2. Scarfing practice: each student grinds a scarf repair bevel on a 300 mm × 300 mm glass/epoxy coupon with a seeded 75 mm diameter hole, targeting the scarf ratio specified in the provided OEM-style repair manual; instructor measures bevel profile at eight radial points with a feeler gauge.
  3. Solvent wipe procedure: students wipe the scarfed surface with the specified solvent (methyl ethyl ketone or isopropyl alcohol per SDS and repair manual), using lint-free wipes in one direction only; instructor inspects with UV light or white glove check for contamination.
4.5-inch angle grinder with 24- and 60-grit discs, vacuum shroud or local exhaust ventilation, hearing protection, disposable Tyvek suit, nitrile gloves, half-mask with P100 cartridge, 300 × 300 mm glass/epoxy coupons with seeded defects, protractor, feeler gauge set, solvent per SDS, lint-free wipes, OEM-style repair manual excerptInstructor measures scarf bevel at eight points; at least six of eight points must be within ±2° of the specified angle, and the glove wipe must show no visible contamination; student retakes surface prep on a fresh coupon if either criterion fails.
7Wet Layup Structural Repair22labStudents will complete a wet-layup structural repair on a scarfed composite panel, placing plies in the correct orientation and sequence per a provided laminate schedule, and produce a cured laminate that passes tap-test and meets thickness tolerance.
  1. Ply-cutting exercise: students cut seven glass-fiber plies to the correct shape and dimension for a stepped scarf repair using scissors and a ply template; each ply is numbered and its fiber orientation marked with a dry-erase marker before layup begins.
  2. Layup: students wet out each ply with mixed epoxy using a foam roller, apply in correct sequence to the scarfed coupon, consolidate with a grooved roller to remove air bubbles, apply peel ply and breather, then close the bag for vacuum-bag cure; instructor observes and records any bagging defects.
  3. Post-cure inspection: after cure, students remove bag, peel ply, and perform tap-test over the entire repair area using a grid; they measure repair thickness at five points with a calibrated digital caliper and record results on the repair card.
Woven and biaxial glass fabric, pre-mixed epoxy system, foam rollers, grooved aluminum consolidation roller, laminate schedule template, ply-cutting template, scissors, peel ply, perforated release film, breather fabric, vacuum bag film, sealant tape, vacuum pump and gauge, digital caliper, repair-card form, tap-test hammerRepair card checked by instructor: tap-test shows no dull areas in the repair footprint (100% clear); thickness at all five measurement points within ±0.5 mm of the laminate schedule target; ply sequence verified from photo log = pass.
8Leading-Edge Erosion Repair and Protective Coating Application18labStudents will prepare a leading-edge blade section, apply a polyurethane or epoxy leading-edge coating to specified wet-film thickness, and install an erosion-protection tape or shell following the manufacturer's overlap and temperature-window requirements.
  1. Leading-edge assessment: students examine a 600 mm blade-leading-edge mockup with staged erosion damage, measure erosion depth with a depth gauge at five stations, record findings on the damage form, and select the appropriate repair level (cosmetic fill vs. full erosion shield replacement).
  2. Coating application: students apply a two-component polyurethane coating to a prepared leading-edge mockup using a foam brush or short-nap roller, check wet-film thickness with a wet-film gauge at three points per square meter, and adjust to meet the specified thickness range.
  3. Erosion-tape installation: students apply a pre-cut erosion-protection tape to the leading edge, using a heat gun to activate adhesive per the manufacturer's instruction sheet, forming around the profile without bridging or air entrapment, and inspect with a roller-press for full contact.
600 mm leading-edge blade mockup, depth gauge, two-component polyurethane leading-edge coating with TDS, foam brush and short-nap roller, wet-film thickness gauge (comb type), erosion-protection tape, heat gun, temperature-indicating sticker, hand roller, damage-assessment formInstructor checks wet-film thickness records (all readings within the manufacturer's specified range = pass) and inspects tape installation for bridging and air bubbles over the full length; any bridging >25 mm or wet-film reading outside range requires section to be redone.
9Cosmetic Fairing and Gel Coat Finish Repair16labStudents will apply a polyester or vinyl ester gel coat filler to a structural repair, feather to the surrounding surface profile using board-sanding, and achieve a final surface finish within ±1 mm of the surrounding airfoil contour as measured by a contour gauge.
  1. Fill and fair: students mix gel coat filler, apply with a squeegee over the cured structural repair, overfill slightly, and allow to cure; after cure they board-sand with progressive grits (80, 120, 220) using a 300 mm rigid backing board to blend the repair into the surrounding surface.
  2. Contour check: students use a flexible contour gauge at five chord-wise stations across the repair to measure the surface profile and compare readings to the undamaged blade surface adjacent to the repair; deviations are marked with a pencil and additional fill/sanding is applied.
  3. Final inspection: students perform a visual inspection under raking light (a handheld flashlight at a low angle) to identify sanding scratches, pinholes, and color mismatch; they document findings with photographs and complete the cosmetic repair sign-off section of the repair card.
Gel coat filler (polyester or vinyl ester), mixing cups, squeegee, 80/120/220-grit sandpaper, 300 mm rigid sanding board, contour gauge, handheld flashlight, repair card, camera or tablet, color-match chartContour gauge readings at all five stations within ±1 mm of surrounding surface = pass; visual inspection shows no pinholes >0.5 mm and no sanding scratches visible under raking light = pass; both criteria must pass.
10Field Repair at Height: Working in a Rope-Access or Platform Context20fieldStudents will prepare and stage composites repair materials for a simulated at-height repair scenario, observing chemical handling, tool-tethering, and waste-management requirements specific to blade work performed on a tower or using rope-access rigging.
  1. Tool-tethering setup: students attach tethers rated for the weight of each tool (angle grinder, mixing cup, roller) to their harness and to the tool using manufacturer-approved anchor points; instructor inspects all connections before any simulated work begins.
  2. Staged at-height mixing drill: on a ground-level elevated platform (simulating a blade-access cradle), students mix a small epoxy batch in a tethered cup, apply to a vertical practice panel, and manage peel ply and vacuum bag on a vertical surface, noting differences from flat-panel layup.
  3. Waste containment exercise: students package used mixing cups, contaminated wipes, and spent PPE into labeled, sealed waste bags following the SDS disposal guidance; they lower the waste package from the elevated platform using a hand-over-hand lowering line and complete the waste-manifest log entry.
Full-body harness (from Tower Climbing course), tool tethers rated for each tool weight, elevated practice platform (ground-level or low), vertical practice panel, tethered mixing cups, epoxy resin batch, vacuum bag kit, waste bags, waste-manifest log, chemical waste labelsInstructor observation: all tools tethered before work begins (no untethered item = pass); epoxy application on vertical panel shows no runs >50 mm (pass); waste properly packaged, labeled, and lowered without spillage (pass); all three must pass.
11Repair Documentation, Material Traceability, and CMMS Entry18practiceStudents will complete a full repair-documentation package—including a damage-assessment report, repair card, material traceability record (batch numbers, mix ratios, cure data), and quality sign-off—and enter the work order into a computerized maintenance management system (CMMS) training environment.
  1. Paper documentation drill: given a completed repair scenario summary, students fill out a four-part paper documentation set (damage form, repair card, material traceability log, QC sign-off) as if they performed the repair, ensuring all fields are complete and traceable.
  2. CMMS data entry: students log into a CMMS training-environment instance (Maximo or equivalent training version), locate the simulated work order for the repair, enter defect description, repair actions, materials used with batch numbers, labor hours, and close the work order with a pass/fail quality result.
  3. Peer review: students exchange completed documentation packages with a partner and use a documentation checklist to identify any missing or inconsistent entries; each student writes a brief correction memo for any discrepancies found, then discusses findings as a class.
Four-part paper documentation kit, CMMS training environment (laptop or tablet, training license), work-order scenario packet, documentation checklist, correction-memo templateInstructor scores paper documentation package (all required fields populated and internally consistent = pass, defined as no more than two minor omissions and zero critical omissions such as missing batch number or cure data); CMMS entry verified by instructor: work order closed with all mandatory fields = pass.
12Integrated Quality Inspection and Repair-Readiness Review16labStudents will conduct a complete quality inspection sequence on a finished composite repair—visual, tap-test, contour, adhesion pull-off (or equivalent), and documentation review—and deliver a verbal findings report, recommending accept, rework, or escalate.
  1. Full inspection sequence: each student receives a completed repair coupon (some passing, some with seeded defects) and performs the full four-step QC sequence (visual, tap-test, contour gauge, pull-off test simulation using a standardized force gauge), recording all data on a QC inspection form.
  2. Disposition decision: based on inspection data, student writes a one-page disposition report recommending accept, rework, or escalate to engineering, citing the specific out-of-tolerance measurement or defect that drives the decision.
  3. Verbal debrief: student presents their findings and recommendation to the instructor and two peers in a structured three-minute report; instructor and peers ask two clarifying questions; student must answer both correctly to complete the exercise.
Set of finished repair coupons (pass and fail examples), tap-test hammer, contour gauge, pull-off force gauge or tactile adhesion tester, QC inspection form, disposition-report template, timerQC inspection form complete with all data recorded; disposition recommendation matches the seeded outcome (correct on at least 3 of 4 coupons = 75% pass); verbal debrief answers both questions correctly; all three criteria must be met.

#LessonHrTypeObjectiveActivitiesMaterialsCheck
1Project Planning, Hazard Analysis, and Documentation Framework40theoryStudents produce a complete pre-job documentation package — scope of work, job hazard analysis (JHA), lockout/tagout procedure, PPE matrix, and tool/material list — for an assigned simulated turbine service task before any hands-on work begins.
  1. Review a realistic turbine service work order and break it into discrete tasks; assign OSHA hazard categories (electrical, fall, struck-by, hydraulic pressure) to each task and record on a JHA form modeled on industry templates.
  2. Draft a site-specific lockout/tagout procedure for the training turbine covering all energy sources (electrical, hydraulic, stored mechanical), have a peer perform an independent review, then reconcile discrepancies against the equipment energy-control diagram.
  3. Build a complete bill of materials and tool list — including torque wrenches, multimeters, manometers, composite repair consumables, and PPE — cross-checked against the manufacturer service manual excerpt; present the completed package to the instructor for a go/no-go gate review.
Sample turbine service work orders, blank JHA forms, LOTO procedure templates, PPE selection guides (ANSI/ISEA references), manufacturer service manual excerpts, NCCER Wind Turbine Tech module reference sheets, GWO BST documentation examples, word-processing and spreadsheet software.Instructor gate review of the documentation package using a rubric with five scored sections (scope clarity, JHA completeness, LOTO accuracy, PPE appropriateness, tool list accuracy); student must score at least 80% overall with no section scoring below 70% to proceed to the hands-on phase.
2Integrated Hands-On Service Execution with Injected Faults108labStudents carry out the full planned maintenance sequence on a training turbine or simulator — including mechanical inspection and torquing, hydraulic system checks, electrical and controls testing, and a composites visual inspection — while responding to at least two instructor-injected faults and recording all findings in real time.
  1. Execute the approved LOTO procedure under observation, then perform the mechanical maintenance tasks (fastener torque verification using calibrated torque wrenches, gear-oil level and condition check, blade-pitch mechanism inspection) and record all readings on the maintenance log using correct units and the pass/fail criteria from the service manual.
  2. Conduct hydraulic system pressure checks with a calibrated gauge, inspect hoses and fittings for condition, and perform electrical/controls tasks — insulation resistance testing, continuity checks, and PLC fault-code reading — using a calibrated multimeter and clamp meter; when the instructor activates a hidden fault (e.g., a miswired control circuit or a simulated hydraulic pressure drop), apply a structured root-cause analysis worksheet to identify the fault and document corrective action.
  3. Complete a composites visual inspection checklist on a blade section (or mock blade panel), classify any defects by type and severity per the repair procedure learned in Course 6, photograph defects with a scale reference, and update the inspection report; at the end of each work session debrief with the instructor using the recorded data to confirm documentation accuracy and flag any safety observations.
Training turbine or full-scale wind turbine simulator, calibrated torque wrenches (ft-lb and Nm ranges appropriate to turbine fasteners), calibrated digital multimeter, clamp meter, insulation resistance tester (megohmmeter), hydraulic pressure gauge and fittings, PLC or turbine SCADA training interface, composites inspection kit (flashlight, mirror, scale, camera), maintenance log forms, root-cause analysis worksheets, full PPE set (hard hat, safety glasses, cut-resistant gloves, arc-flash rated clothing where required, harness if elevated work is performed), NCCER Wind Turbine Tech module competency checklists.Instructor uses a real-time performance checklist (based on NCCER Wind Turbine Tech task lists) to observe each major task; any critical safety violation (skipping LOTO, working at height without a secured harness) results in an immediate stop and automatic remediation requirement; at lesson end, maintenance log and fault-diagnosis worksheet must be 85% complete and accurate to advance; torque values must be within the service manual tolerance.
3Documentation Completion, Self-Assessment, and Remediation Planning32practiceStudents finalize all project documentation into a cohesive job package, perform a structured self-assessment against NCCER Wind Turbine Tech and GWO BST competency areas, and produce a written remediation plan targeting identified gaps before the Externship.
  1. Compile the JHA, LOTO procedure, maintenance log, torque records, electrical test data sheets, fault-diagnosis report, and composites inspection report into a single numbered, indexed job package; cross-check every numerical entry for unit correctness and legibility, using the trade-math skills from Course 1 to verify calculated values (e.g., converting torque units, confirming Ohm's-law relationships in recorded electrical data).
  2. Use an instructor-provided self-assessment matrix that maps each NCCER Wind Turbine Tech module topic and each GWO BST module (Working at Heights, First Aid, Manual Handling, Fire Awareness, Sea Survival if applicable) to capstone tasks; rate personal performance on each item, flag items rated below satisfactory, and gather supporting evidence from the job package.
  3. Write a one-to-two-page remediation plan that lists each gap, identifies which Course 1–6 content addresses it, proposes a specific self-study or practice action, and sets a target completion date before the start of the Externship; submit the plan to the instructor for written feedback.
Full project documentation from Lesson 2, NCCER Wind Turbine Tech module competency checklists, GWO BST module learning objectives list, self-assessment matrix template, trade-math reference sheet (unit conversions, Ohm's law, pressure formulas, torque formulas), word-processing software, document binder or digital portfolio platform.Instructor reviews the completed job package for completeness (all required sections present), accuracy (at least 85% of numerical entries correct), and professional presentation (legible, properly labeled, indexed); the self-assessment matrix must have an entry for every listed competency area; the remediation plan must address every item rated below satisfactory — all three elements must meet the standard before the student is cleared for the oral defense.
4Technical Defense and Capstone Panel Presentation36demoStudents deliver a structured 15-minute oral defense of their capstone project to a panel of at least two evaluators, explaining task decisions, safety choices, fault-diagnosis reasoning, and documentation methods, then respond to panel questions at a level that demonstrates job-entry readiness.
  1. Prepare and rehearse a 15-minute structured presentation (slides or whiteboard permitted) covering: project scope, pre-job hazard controls chosen and why, key maintenance findings, fault-diagnosis process and root-cause conclusion, composites findings, and one lesson learned; practice with a peer in a timed run-through and incorporate feedback.
  2. Deliver the presentation to the panel (at minimum: lead instructor and one industry or faculty guest evaluator); use the actual job-package binder as a reference and point to specific records when citing data — panel members may interrupt with technical questions at any point, including questions drawn from NCCER Wind Turbine Tech and GWO BST competency areas.
  3. After the defense, complete a brief written reflection (one page maximum) identifying the single most important safety decision made during the project and explaining, using OSHA 10 and GWO BST principles, why that decision was correct; submit the reflection as the final artifact in the portfolio.
Completed job-package binder, presentation software or whiteboard, panel evaluation rubric (shared with student in advance), NCCER Wind Turbine Tech competency area list for panel reference, GWO BST module list for panel reference, timer.Panel scores the defense on a rubric with five equally weighted sections: technical accuracy of explanations, safety and LOTO knowledge, fault-diagnosis reasoning, documentation literacy (ability to locate and explain records), and professional communication; student must score at least 80% overall with no section below 70%; a score below threshold requires one remediation session and a second defense within five business days.

1GWO Basic Safety Training Domain Review20theoryStudents will answer GWO Basic Safety Training practice questions across all five modules—manual handling, working at height, fire awareness, first aid, and sea survival—scoring at least 80% on a module-by-module diagnostic.
  1. Instructor-led domain walkthrough: for each of the five GWO modules, review the published learning objectives from GWO's Basic Safety Training standard, then work through scenario-based practice questions as a class, discussing why each distractor is wrong using the GWO BST syllabus and course materials from earlier program units.
  2. Small-group stations: groups rotate through five tabletop stations (one per module), each containing a 15-question timed set drawn from GWO content areas; groups record answers on bubble sheets, self-score with the provided answer key, and flag questions where the group was split or unsure.
  3. Individual diagnostic quiz: each student completes a 50-question timed GWO-format diagnostic (10 questions per module), scores it against the key, enters results into a personal Exam Readiness Tracker spreadsheet by domain, and identifies the two modules with the lowest scores for targeted review.
GWO Basic Safety Training standard (current version, gwo.org), program unit 1 and unit 5 student notes, printed 50-question diagnostic with answer key, Exam Readiness Tracker spreadsheet template, whiteboard, projectorScored diagnostic quiz by module; pass standard is 80% overall with no single module below 70%. Students below threshold in any module receive a written remediation assignment before Lesson 3.
2NCCER Wind Turbine Technician Exam Domain Review28theoryStudents will correctly answer NCCER Wind Turbine Technician practice questions covering orientation, safety, tools and equipment, electrical systems, mechanical systems, hydraulics, and tower systems at a rate of 70% or higher on a full-domain diagnostic.
  1. Domain mapping exercise: students receive a printed list of NCCER Wind Turbine Technician module titles and, working in pairs, match each item to the program course in which it was taught, then identify the NCCER module number and primary performance task associated with each domain—anchoring exam content to hands-on experience from Courses 2 through 7.
  2. Instructor-facilitated worked-example session: using NCCER's Contren curriculum structure as a guide, the instructor projects representative multiple-choice and performance-task questions from each module family (electrical, mechanical, hydraulic, tower), solves each aloud using trade reasoning, and invites students to challenge or confirm the logic before revealing the answer.
  3. Individual 80-question timed NCCER-format practice exam: students work under timed conditions (one question per 90 seconds), submit answer sheets, receive domain-coded score reports broken out by module family, update their Exam Readiness Tracker, and write a one-page gap-analysis memo identifying their three weakest NCCER domains and listing the specific NCCER module pages and program lab exercises they will revisit.

Students below threshold in any module family complete assigned NCCER module re-read and a 10-question targeted quiz before Lesson 4.
3OSHA 10 Content Review and Hazard Recognition Practice17theoryStudents will correctly identify OSHA 10 outreach content areas—including hazard recognition, fall protection, electrical safety, struck-by and caught-in hazards, PPE selection, and emergency action plans—and score 70% or higher on a timed OSHA 10 practice assessment.
  1. OSHA 10 content card sort: students receive a set of 40 laminated scenario cards (e.g., 'technician works above 6 feet without a personal fall arrest system') and sort them into OSHA topic categories, then cite the relevant general duty or construction standard category for each hazard—reinforcing the habit of connecting hazard observation to the regulatory framework learned in Course 1.
  2. Case-study analysis: in groups of three, students read four one-page incident summaries drawn from publicly available OSHA enforcement news releases involving wind energy or tower work, identify every OSHA violation present, select the correct hazard category from the OSHA 10 outline, and present findings to the class for instructor correction and discussion.
  3. Individual 50-question timed OSHA 10 practice assessment: students complete the assessment under timed conditions, receive a domain-coded score report, and confirm their OSHA 10 outreach program enrollment status with the program's OSHA-authorized trainer to ensure all administrative requirements (attendance hours, authorized trainer signature) are on track.

Students below threshold review the relevant OSHA 10 topic sections with the authorized trainer and complete a targeted 15-question re-quiz before the mock exam day.
4Full Mock Certification Exam Day and Personalized Remediation25practiceStudents will sit full-length, timed mock versions of all three credentials under simulated proctored conditions, score at or above each credential's pass standard, and complete a written post-exam action plan addressing any remaining gaps before their scheduled live exams.
  1. Simulated exam day (Morning session): students sit a full-length GWO BST mock assessment followed by a full-length OSHA 10 mock assessment back-to-back under proctored conditions with no notes, phones silenced, and a visible countdown timer; the instructor acts as proctor, collecting answer sheets at time, grading them during break, and returning scored reports with domain breakdowns before lunch.
  2. Simulated exam day (Afternoon session): students sit the full-length NCCER Wind Turbine Technician mock exam under the same proctored conditions; after time is called, the instructor guides a whole-class debrief using a projected answer key, explaining the trade reasoning behind the five most-missed questions across the group and reinforcing the elimination strategy for similar question types.
  3. Individual post-exam action plan: each student receives all three scored mock reports, updates their Exam Readiness Tracker with final mock scores, writes a structured one-page action plan specifying which domains still need work, which materials they will use (NCCER module, GWO syllabus section, OSHA topic), how many hours they will self-study before each live exam, and the date they have scheduled or will schedule each credential assessment; the instructor reviews and signs off on every plan.
