InterNACHI Well exam-day guide
InterNACHI Well · Prepare for the day ahead.
Your checklist
Government-issued photo ID
Bring the same name and spelling used on your registration. If your registration used a different form of your name, confirm with the provider before test day how name mismatches are handled.
Your exam appointment confirmation
Know your appointment time, the provider's name, and whether the exam is delivered online with a proctor or at a physical test center. Save the confirmation email or screenshot it so you can access it without a network connection.
Login and system check completed in advance
If the exam is remotely proctored, run any required system or equipment check and install any required browser extension or secure browser ahead of time. Confirm with the provider which browsers and operating systems are supported.
Reliable internet and a backup plan
For remote delivery, use a wired or stable connection and have a phone hotspot or second device ready. Confirm with the provider what happens if your connection drops mid-exam, including whether the attempt is paused or voided.
Webcam, microphone, and speakers
Remote proctoring typically requires a working camera and microphone, and often a room scan. Test them the day before. Confirm with the provider whether a headset is allowed or prohibited.
A quiet, private, well-lit room
Plan a space with a door you can close, no other people entering, and a clear desk. Proctors commonly flag movement, background voices, or a second screen. Confirm with the provider the specific room and desk requirements.
Knowledge of permitted reference materials
Many inspection certification exams are closed-book. Confirm with the provider whether any code book, standards document, calculator, or scratch paper is allowed, and whether scratch paper must be blank and shown to the proctor.
Exam blueprint and topic weights reviewed
Know the domains and approximate weighting before you sit down so you can pace yourself. If the provider does not publish weights, treat all domains as equally weighted and budget time accordingly.
Core well and water-system concepts rehearsed
Be ready to reason about well types, pump and pressure-tank components, pressure switch settings, water quality and testing, and the limits of a well inspection under applicable standards. Rehearse explaining what is and is not within the scope of a well inspection.
Photocopied or handwritten one-page summary (if permitted)
Only bring notes if the provider allows them. If notes are prohibited, use the summary for last-minute review before the session starts and put it away. needs_review: confirm with the provider whether any notes are permitted in the testing environment.
Water and a light snack for before the exam
Eat and hydrate before you begin. Keep food and drink off the desk unless the proctor permits them; confirm with the provider whether drinks are allowed during the session.
A plan for breaks and restroom use
Use the restroom before you start. Confirm with the provider whether scheduled or unscheduled breaks are allowed, whether the clock keeps running, and whether leaving the camera view during a remote exam ends the session.
Plan the day
Re-read the exam blueprint or content outline and list the domains where you are weakest. Spend your remaining study time on those domains rather than re-reading material you already know. Confirm your appointment details, the delivery format, and any technical requirements with the provider, and resolve any open questions about ID, permitted materials, and breaks now rather than on test day.
Do practice questions under timed conditions in one sitting so you get used to sustained concentration. Review every miss by writing the correct reasoning in your own words. For well content, practice distinguishing what an inspector can observe and report from what requires a licensed well contractor, pump installer, or laboratory analysis.
Run the full technical check for remote delivery: camera, microphone, browser, and internet stability. Identify a backup device and connection. If you are testing at a center, confirm the address, parking, arrival time, and what you may bring into the room.
Do a light review only: key terminology, component functions, and the scope-and-limitations points you tend to confuse. Stop studying early enough to sleep well. Prepare your ID, confirmation, and any permitted items in one place. Set two alarms and plan to arrive or log in early.
Eat a normal meal, hydrate, and avoid cramming new material. Clear your desk and room if testing remotely, close extra applications, and silence notifications and phones. Log in or arrive with time to spare so a technical or check-in problem does not eat into your exam time.
Read each question fully and watch for qualifiers such as 'best', 'first', 'except', and 'minimum'. Answer the questions you know first, flag uncertain ones, and return to them if the platform allows review. For scenario questions, ask what an inspector can actually observe, what should be reported, and what should be referred to a qualified specialist. Keep an eye on the clock and leave time to review flagged items.
Note which topics felt weak while they are fresh. If the provider gives a score report with domain breakdowns, use it to plan any required continuing education or a retake. Confirm with the provider how and when results are delivered and what the retake policy is.
Rules to check
Bring government-issued photo ID matching your registration and present it when asked. If your ID name differs from your registration, contact the provider before test day; do not assume the proctor can resolve it.
Follow the provider's rules on permitted materials exactly. Assume the exam is closed-book unless the provider states otherwise, and keep phones, smart watches, and other devices away from the testing area.
For remotely proctored exams, stay in camera view, keep your face visible, and avoid talking, reading aloud, or leaving the room. Confirm with the provider in advance how breaks and restroom use are handled.
Do not communicate with anyone about exam content during the session, and do not share, record, or reproduce exam questions afterward. Treat the content as confidential under the provider's agreement.
Understand how scoring works before you begin: confirm with the provider whether there is a passing score, whether questions are weighted, whether wrong answers are penalized, and whether you can review or change answers.
Know the time limit and whether it includes check-in, instructions, and breaks. The clock may keep running during any allowed break; confirm with the provider.
If a technical failure occurs, stop and follow the proctor's or support line's instructions immediately, and note the time. Confirm with the provider how incidents are documented and whether an affected attempt can be reset.
Report any suspected error in a question to the provider after the exam rather than arguing it during the session. Confirm with the provider how challenges to exam content are submitted.
