Integrated Structure Assessment: Mock Inspection, Deficiency Documentation, and Referral Decisions
Objective. Working independently, the student will complete a timed mock structural inspection of a pre-set training scenario, produce a written findings narrative, and correctly classify each finding by severity and referral type at a level meeting InterNACHI CPI and ASHI ACI exam expectations.

Why This Lesson Matters
A home inspector's final product is not what they saw — it is what they wrote. Clients, real-estate agents, lenders, and attorneys rely on your written report to make decisions involving hundreds of thousands of dollars and, in some cases, personal safety. This practice lesson brings together every structural concept from the course into a single timed exercise that mirrors real inspection work and the expectations of the InterNACHI CPI and ASHI ACI credentialing bodies.
The Timed Mock Inspection
During the 60-minute timed period you will move through a training scenario containing at least eight seeded structural conditions spread across four systems: foundation, floor framing, wall framing, and roof structure. Treat this exactly as you would a real inspection — no instructor coaching is available once the clock starts.
Work systematically. Begin at the exterior foundation, move to the crawlspace or basement, then walk the floor system, examine walls for racking or damage, and finish in the attic with the roof structure. A methodical sequence prevents missed areas and mirrors the logical flow that InterNACHI and ASHI both expect an inspector to follow.
Use every tool you have. Your flashlight, probe, tape measure, 4-foot level, moisture meter, and camera are all in play. If you skip a tool, you are likely to miss a condition. Probe wood members in crawlspaces and attics where moisture readings are elevated — soft wood under probe pressure is a red flag for decay or insect damage. Check bearing walls with your level for out-of-plumb conditions. Photograph every finding before you move on; photo numbers become your report's evidence chain.
Safety posture during the inspection. Before entering any crawlspace or attic: confirm adequate ventilation or use a dust/particulate respirator (N95 minimum) where insulation fibers are present; wear knee pads and a hard hat where headroom is limited; watch your step on ceiling joists — walk only on framing members, never on insulation between joists. Keep your phone charged and accessible. If you encounter an unexpected hazard (standing water near electrical panels, visible animal activity, or severely compromised framing that feels unsafe to approach), back out and note the limitation in your report — inspectors are not required to enter areas that present a risk to their safety.
Writing the Findings Narrative
The 45-minute writing period tests whether you can translate field observations into clear, neutral, professional language. Organize your narrative by system, not by severity. Within each system, list findings in the order you encountered them and reference the photo number that supports each.
The Four Classification Terms
You must use the correct term for each condition:
No deficiency observed — the component was inspected and appeared serviceable. This statement is not filler; it protects you legally and informs the client.
Monitor — a condition that is not immediately deficient but warrants watching at the next maintenance cycle. Example: a very minor diagonal crack in a concrete block foundation with no displacement and no moisture intrusion.
Repair — a deficiency a qualified contractor can correct without a licensed engineer's design. Example: a split rim joist that can be sistered.
Further evaluation by a qualified structural engineer — required when the inspector cannot determine the cause, extent, or structural consequence of a condition, or when a life-safety concern exists. This is the most important classification in the lesson. Under-calling this referral — for example, writing "monitor" for a bearing wall that shows signs of lateral displacement — is a serious professional and legal error. Both InterNACHI and ASHI Standards of Practice require inspectors to recommend specialist evaluation when a finding exceeds the scope of a general inspection.
Neutral Descriptive Language
Avoid alarmist or minimizing words. Do not write "the house is falling down" or "just a tiny crack." Write what you observed: location, size, orientation, and any associated symptoms. Example: "A diagonal crack approximately 3/8 inch wide was observed at the southeast corner of the poured-concrete foundation wall, extending from the top of the wall downward approximately 14 inches. Efflorescence was present along the crack face. Evaluation by a qualified structural engineer is recommended to determine cause and required repair."
Self-Assessment and Instructor Debrief
After the writing period, you will score your own narrative against the InterNACHI report-writing rubric before the instructor reveals the seeded conditions. Honest self-scoring is a professional skill — inspectors who cannot recognize their own gaps cannot improve them.
The debrief maps every seeded condition to the specific InterNACHI CPI and ASHI ACI exam domains you will encounter on credentialing assessments: Foundation Systems, Structural Components, Crawlspaces, and Attics. Know these domain names. Exam questions are organized around them, and your license application may reference the same categories.
Scoring and the Life-Safety Rule
Your narrative is scored on a 100-point scale: up to 60 points for identifying at least 6 of the 8 conditions, and 40 points for language and classification accuracy. Passing is 70 or higher.
One rule overrides the point total: any student who misclassifies a life-safety structural concern receives mandatory one-on-one remediation regardless of their score. This reflects real-world consequences — an inspector who fails to refer a compromised bearing wall to an engineer exposes a client to structural collapse and exposes themselves to license discipline and civil liability. Credential exams penalize the same error; know the line between "repair by contractor" and "engineer referral required."
Key terms10
Bearing wallA wall that carries vertical loads from the structure above it down to the foundation; damage or removal without engineering review is a life-safety concern.
Engineer referralA written recommendation in the inspection report that a licensed structural engineer evaluate a condition that is beyond the scope of a general home inspection or that poses a potential life-safety risk.
EfflorescenceWhite mineral deposits left on masonry or concrete surfaces when water moves through the material and evaporates, indicating moisture intrusion rather than structural failure by itself.
SisteringA repair method in which a new framing member is fastened alongside a damaged or undersized member to restore or supplement its load-carrying capacity.
Out-of-plumbA condition in which a vertical structural member such as a wall or column leans from true vertical, detectable with a level or plumb bob.
Neutral descriptive languageReport writing that states observable facts — location, size, orientation, associated symptoms — without alarmist or minimizing characterizations, as required by InterNACHI and ASHI reporting standards.
InterNACHI Standards of Practice (SOP)The published document that defines what a Certified Professional Inspector is required to inspect, what must be reported, and what is outside the scope of a residential inspection.
ASHI Standards of PracticeThe American Society of Home Inspectors' published document establishing minimum inspection scope and reporting requirements for member inspectors and the ACI credential.
Rim joistThe outermost joist running along the perimeter of a floor frame that closes off the ends of the floor joists and transfers loads to the foundation or sill plate.
Seeded conditionA defect or deficiency intentionally placed in a training scenario so students can practice identifying, classifying, and documenting it under realistic inspection conditions.
In class: Timed 60-minute mock inspection of a classroom or training-site scenario with at least eight seeded conditions across foundation, floor framing, wall framing, and roof structure; students use all tools and their completed checklists from prior lessons — no instructor coaching during the timed period — to replicate real exam and real-work conditions. · Findings-narrative writing period (45 minutes): students draft a short written structural section of a home-inspection report, organizing findings by system, using neutral descriptive language, correctly applying the terms 'monitor,' 'repair,' 'further evaluation by a qualified structural engineer,' and 'no deficiency observed,' and attaching photo references by number. · Structured self-assessment and instructor debrief: students score their own narratives against the InterNACHI report-writing rubric, then the instructor leads a whole-group review of each seeded condition, correct classification, and the specific InterNACHI or ASHI exam domains each condition maps to (foundation systems, structural components, crawlspaces, attics), reinforcing exam vocabulary students will see on certification assessments. Materials: Training scenario with eight seeded structural conditions, all personal inspection tools (flashlight, probe, tape, level, moisture meter, camera), blank report-narrative template, InterNACHI report-writing rubric, InterNACHI Standards of Practice, ASHI Standards of Practice, exam-domain mapping handout cross-referencing lesson content to InterNACHI CPI and ASHI ACI structural inspection exam areas Check: Instructor scores the narrative using the InterNACHI report-writing rubric: identification of at least 6 of 8 conditions (60 pts possible at 10 pts each) plus narrative language and classification accuracy (40 pts). Pass = 70 of 100. Any student who misclassifies a life-safety structural concern (e.g., failing to recommend engineer evaluation for a compromised bearing wall) receives mandatory one-on-one remediation regardless of total score.
