Blueprint-weighted
Every domain the ACAC blueprint tests.
Questions are distributed across the published weights — not evenly. Your team spends time where the exam actually grades.
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+ CIEC practice questions unlocked per seat — free-response, calculation, and scenario items.
Blueprint-weighted practice
Questions served in the ACAC published weights across the 6 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We do not publish named customer stories.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 CIEC 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.

Three ways to see CIEC in action.
Pick whichever gets you to a yes fastest.
Failing the CIEC means another application cycle, another sitting fee, and weeks of stalled proposals where clients hire the consultant who already has the credential.
Every question is mapped to a specific ACAC blueprint task and explains not just the right answer but the instrument limitation, sampling caveat, or standard citation a defensible report would need — something free PDFs and recycled HVAC quizzes don't touch.
Common questions
- How closely do these questions match the real ACAC CIEC exam?
- Every item is written against the current ACAC CIEC Candidate Handbook blueprint and tagged to one of the six domains at their published weights — 17% IAQ contaminants, 17% built environment, 17% HVAC, 16% instrumentation, 16% standards, 17% investigation and remediation. The 120-question, 180-minute, 75%-to-pass format is mirrored in our timed mode so your pacing on exam day is already calibrated.
- I work in mold remediation, not HVAC. Will this fill my gaps?
- Yes — that's exactly the candidate this bank is built for. Roughly a third of the exam covers HVAC systems and instrumentation, and rationales explain psychrometrics, airflow measurement, and equipment limitations from first principles rather than assuming a mechanical background. You'll also get reinforcement on the standards and built-environment domains where remediation specialists tend to under-prepare.
- Individual license vs. team seats — what's the difference?
- The $109 individual license gives one candidate full access to the question bank, timed practice exams, and rationale library through their attempt. Team seats at $59 each are for firms enrolling multiple staff and include a manager dashboard to track per-domain readiness across candidates. Retake policies and ACAC application fees are set by ACAC, not us — check their site for current numbers.
