InterNACHI Septic exam-day guide
InterNACHI Septic · Prepare for the day ahead.
Your checklist
Government-issued photo ID
Bring the original, unexpired ID with a name matching your registration exactly. If your registration name differs even slightly (middle name, hyphenation), contact the provider before test day to correct it. Confirm with the provider which ID forms it accepts.
Log-in credentials and exam access link
Know your username and password for the testing or proctoring platform, and have the exam access link or launch instructions saved offline. If your exam is delivered through InterNACHI's online education platform, sign in ahead of time to confirm the course appears in your account. Confirm the exact launch procedure with the provider.
Computer, webcam, microphone, and charger
If testing remotely, use a reliable computer with a working webcam and microphone for proctoring, and keep the charger plugged in. Run any required system or equipment check in advance rather than on exam morning.
Stable internet and a quiet, private room
Plan a location with dependable internet and no interruptions. Remote proctoring typically requires you to be alone in the room, so arrange child care, pet care, and household quiet for the exam window.
Clean desk and clear surroundings
Remove papers, notes, phones, smart watches, and extra screens from the testing area unless the provider's rules allow them. Proctors commonly require a room scan, so set up a space that is easy to show on camera.
Review your course materials and notes
Re-read your septic inspection course notes, especially treatment systems, drainfield and soil evaluation concepts, dosing and pump systems, and inspection reporting. Use practice quizzes to find weak areas rather than re-reading everything.
Confirm exam logistics with the provider
Verify the exam format, number of questions, time limit, passing score, number of attempts, retake policy, and any proctoring fees directly with InterNACHI or the testing provider. Do not rely on secondhand reports of these details.
Know the technical setup and allowed materials
Confirm whether the exam is open-book or closed-book, whether a calculator or scratch paper is permitted, and how to flag or revisit questions in the testing interface. These policies vary, so confirm with the provider.
Plan your time and arrival
Log in or arrive at the test site early to absorb check-in and identity verification. For in-person testing, confirm the address, parking, and arrival window with the test center.
Water, snack, and a rested start
Sleep well the night before and keep water nearby if breaks and desk rules permit. A short walk and a calm review of key terms beat last-minute cramming.
Plan the day
Confirm your exam appointment, access link, and any proctoring requirements in writing from the provider. Recheck your ID name against your registration and fix any mismatch now. Take one or two practice quizzes under timed conditions to identify weak topics, then spend your remaining study time on those topics only.
Review the technical content most likely to be tested: septic system components and flow, tank sizing and baffles, drainfield and soil/perc concepts, dosing and pump systems, aerobic treatment units, signs of failure, and how to document findings in a report. Re-read your own course outlines and notes rather than outside summaries.
Run the full equipment and system check if testing remotely, including webcam, microphone, browser, and internet. Charge devices, clear your desk, and set out your ID. Do a light review of key terms and definitions, then stop studying early enough to sleep a full night. Confirm the start time and time zone.
Eat a normal meal, avoid heavy caffeine if you are prone to jitters, and log in or arrive with time to spare for check-in. Have your ID and log-in details within reach. Do a final skim of a one-page list of key terms, not a full re-read of the course.
Read each question fully and watch for qualifiers such as 'most likely', 'best', or 'except'. Answer the questions you know first, flag and return to harder ones, and watch the clock so you leave time to review. For scenario questions, think in terms of what an inspector would observe, document, and recommend, and remember that inspectors report conditions and defer to qualified specialists rather than prescribing repairs. If a technical glitch occurs, note the time and contact the proctor or provider support immediately rather than continuing silently.
Rules to check
Present the original government-issued photo ID whose name matches your registration. If your name or ID type is uncertain, confirm accepted forms with the provider before test day.
Follow all proctoring and conduct rules: stay in view of the camera, keep the room private, do not talk to others, and do not use phones, notes, or unauthorized materials unless the provider explicitly allows them.
Do not attempt to copy, photograph, record, or share exam questions. Exam content is confidential, and sharing it can void your result and affect your certification standing.
Confirm with the provider whether the exam is open-book and which reference materials are allowed, and stay within those limits.
Ask the provider in advance about scheduled breaks and whether unscheduled breaks are permitted during a remotely proctored exam, since leaving the camera view may end the session.
Understand the scoring and retake rules before you begin: number of questions, passing score, time limit, and how many attempts you get. These specifics vary, so confirm them with the provider rather than assuming.
If your connection drops or the platform fails, do not keep guessing at the problem. Contact proctor or provider support right away and document what happened so the attempt can be reviewed.
If you are unsure of a technical fact during the exam, reason from inspection principles and choose the answer that reflects proper observation and reporting rather than guessing at a code or specification you cannot verify.
