What you get

A prep stack and a training-record stack.

Five things ship on day one. No add-on upsells, no stitching together screenshots when HR or procurement asks for the file.

  • Full question bank

    All 120+ CMC practice questions unlocked per seat — free-response, calculation, and scenario items.

  • Blueprint-weighted practice

    Questions served in the ACAC published weights across the 5 domains, so hours go where the exam actually grades.

  • Rationales on every answer

    Plain-English rationale for both the correct answer and each distractor. Self-explanation prompts preserve the candidate's reasoning on missed items.

  • Team admin dashboard

    One console: enrolment, study hours, mock history, domain mastery, calibration score. Know who is ready, who is stalled.

  • Per-employee training-record export

    Signed PDF per employee per cert. ACAC Competence Evidence Summary v1 header band. The same dossier HR, procurement, and insurance reviewers ask for when they want evidence of EHS-program investment.

How our teams pass

Pass rates above the ACAC national average — once candidates clear the 70% calibration threshold.

We do not publish named customer stories. The honest pattern: candidates who clear 75% on at least two of their last three calibrated mock exams pass the live CMC at a rate above the official ACAC national average. Miss the calibration threshold and we do not certify them ready — the dashboard flags re-work domains, not fake green ticks.

Failing the CMC means weeks of restudy, another application cycle through ACAC, and showing up to mold inspections with credentials your competitors already have.

Every question is mapped to a specific ACAC CMC domain and task, with rationale that explains the defensible protocol — not just which letter is correct — so you learn to justify the call to a lawyer, not just a proctor.

Common questions

How is this different from the ACAC candidate handbook and reference list?
The ACAC handbook tells you what's on the exam; it doesn't drill you on it. Our question bank converts every domain and task in the blueprint into scenario-based items with answer rationale, so you're testing recall and judgment the way the exam does. Use the handbook to scope, use this to prepare.
Does the CMC exam include scenario and case-study questions?
Yes. A large share of the 120 questions present a building, occupant complaint, or sampling result and ask for the defensible next step. Our bank mirrors that format across investigation, sampling, and remediation domains rather than relying on flat definition recall.
I work in remediation, not assessment. Will this prep cover what I'm weakest on?
Yes — that's the most common gap. Remediation-side candidates tend to lose points on Microbial Morphology and Ecology and on Principles of Microbial Investigation, which together account for 45% of the exam. The bank weights questions to the official domain percentages so you spend the most time where the exam does.
