How This Practice Test Works
- Each attempt draws 15–20 questions at random from our pool of 161 and shuffles the answer order. Score 80% or more and the next test moves up a difficulty level; under 50% and it eases back.
- After every answer you see an explanation and the 40 CFR 763 reference behind it.
- We use 70% as a practice target. EPA's Model Accreditation Plan sets a 70% pass mark on a closed-book exam. Aim for 85% or better here.
- There is no sign-up. Your level is saved only in this browser.
These are original questions written by our editorial team from the published 40 CFR 763. They are not real exam questions. Questions follow the AHERA rule and its appendices. Hands-on skills and state-specific rules are taught in your accredited course.

How Difficulty Is Spread Across the Pool
Each question is tagged Foundation, Intermediate or Advanced, and each new test favors questions close to your current level that you have not seen yet in this browser. This is how the 161 AHERA Asbestos questions divide:
| Level | Questions | Share of Pool |
|---|---|---|
| Foundation | 41 | 25% |
| Intermediate | 92 | 57% |
| Advanced | 28 | 17% |
Because unseen questions come first, repeated attempts work through the pool rather than repeating the same items. Note the reference on every miss and reread that section before your next attempt.
