CAHPI National Exam (CNE) common mistakes
CAHPI National Exam (CNE) · Understand the traps and how to avoid them.
Reporting on systems and components that fall outside the CAHPI/CSA A770 scope or that were concealed or not readily accessible, instead of stating the limitation and the reason for not inspecting.
Candidates carry over habits from general construction knowledge and feel obligated to comment on everything visible, forgetting that the Standards of Practice define a minimum, not a maximum, scope and that excluded items must be named as excluded.
What to do instead
Memorize the scope and exclusion clauses of the applicable standard and practise writing limitation statements for concealed, obstructed, or unsafe items. In every practice report, explicitly list what was not inspected and why, and keep commentary within the defined systems.
Describing a defect without stating its implication, or conversely recommending a specific repair method and contractor, rather than recommending evaluation by a qualified specialist.
Candidates confuse the inspector's reporting duty with the role of a contractor or engineer, and they worry that a bare observation looks unhelpful, so they drift into prescribing remedies.
What to do instead
Use a consistent three-part sentence pattern: observation, implication, recommendation. Cap recommendations at 'further evaluation by a qualified specialist' and remove brand names, prices, and repair procedures from practice reports.
Accepting a gift, referral fee, or paid work from a real estate agent or other party with a financial interest in the transaction, or failing to disclose such a relationship in writing.
Candidates underestimate how ordinary-sounding arrangements, such as agent-supplied lunch, marketing help, or a share of a repair referral, breach impartiality, and they assume disclosure only matters for direct employment.
What to do instead
Study the Code of Ethics clauses on conflict of interest, remuneration, and disclosure, then draft a written disclosure and refusal script for the common scenarios. Treat any benefit from an interested party as prohibited and document the refusal.
Softening or omitting a material defect in the report because the client is anxious to close, or discussing findings with the seller or agent before the client has received the report.
Candidates want to be agreeable and avoid conflict, and they misread confidentiality as applying only to the fee, not to the findings themselves.
What to do instead
Rehearse delivering adverse findings plainly and without apology, and confirm in writing that the report belongs to the client. Practise stating that findings will be released to the client first and to no one else without consent.
Misjudging the service life or safety significance of roofing, foundation, and drainage conditions, such as calling a hairline shrinkage crack structural or missing a deficient downspout discharge that undermines the footing.
Candidates rely on visual impressions and textbook images rather than a systematic cause-and-effect analysis of water management and load paths, so they over-call cosmetic items and under-call systemic ones.
What to do instead
Build a decision checklist for each major system that starts with water and load paths, and practise classifying cracks by width, displacement, and pattern. Write a one-line rationale for every defect call and review it against that checklist.
Failing to test or operate safety devices and distribution equipment correctly, such as not testing GFCI and AFCI protection, not verifying bonding of metal piping, or not checking for double-tapped breakers and improper panel clearances.
Candidates are uneasy around energized equipment and skip steps, or they test in the wrong order and reset devices without recording the result, losing the evidence.
What to do instead
Memorize a fixed electrical inspection sequence from service entrance to panel to devices, and practise it on a de-energized training panel until it is automatic. Record each test result and the device location as you go.
Missing combustion safety and venting problems, such as backdrafting at a water heater flue, a cracked heat exchanger, or a return-air path that depressurizes the combustion appliance zone.
Candidates focus on the appliance itself and not on the interaction between the appliance, the vent, and the house as a pressure system, and they lack confidence using a draft gauge or smoke pencil.
What to do instead
Learn the pressure-boundary concept and practise a combustion appliance zone test sequence, including worst-case depressurization and spillage checks. Report any spillage or backdrafting as a safety concern requiring immediate evaluation.
Writing conclusions that are vague or non-actionable, such as 'roof appears serviceable' or 'some moisture noted', with no location, no condition, and no implication.
Candidates draft reports from memory after the inspection and hedge to avoid liability, which produces statements that neither inform the client nor demonstrate the reasoning behind the call.
What to do instead
Adopt a report template that forces location, observation, implication, and recommendation for every finding, and take field notes room by room so the report is written from evidence rather than recollection. Review each line for specificity.
Producing a report with missing or inconsistent administrative content, such as absent scope and limitations, no statement of standards used, unclear inspection date, or unsigned agreement terms.
Candidates concentrate on technical findings and treat the administrative sections as boilerplate, so they omit the very clauses that define the engagement and protect both parties.
What to do instead
Build a pre-delivery checklist covering scope, standards referenced, limitations, exclusions, confidentiality, and signature, and run every practice report through it before submission.
Losing control of the on-site process by allowing the client or agent to direct attention, rush the walkthrough, or negotiate findings, resulting in skipped areas and undocumented conditions.
Candidates want to appear cooperative and lack a rehearsed routine, so interruptions break their inspection sequence and they never return to skipped components.
What to do instead
Follow a fixed exterior-to-interior route with a written component checklist, and use a prepared script to set expectations at the start about access, questions, and when findings will be discussed. Mark each component as inspected before moving on.
