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.
This lesson, its worked examples and its practice questions has not yet been verified by a credentialed professional in the field or by a certification or approval body. It is a study draft and may contain errors. Do not use it as instructions for work on a job site or on live equipment. Always follow your instructor, your supervising professional, and current official references and regulations.
VoTechWorks program approval and accreditation are still in progress. Credentials are issued only by the certifying bodies named in each program, after their own exams.
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.
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.
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.
You must use the correct term for each condition:
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."
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.
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."
Answer each question, then check it. Nothing is recorded; this is your own practice.

Does the school offer financial aid?
No. We don’t offer financial aid because we’re free. No, really: completely free.
Do you offer industry certification?
No. We are not certified yet, so we can’t offer that to students. What we do offer is knowledge and understanding of a trade.
