Blueprint-weighted
Every domain the ABHP 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 150+ CHP practice questions unlocked per seat — free-response, calculation, and scenario items.
Blueprint-weighted practice
Questions served in the ABHP 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. ABHP Part I Preparation Evidence 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 ABHP national average — once candidates clear the 70% calibration threshold.
We do not publish named customer stories. The honest pattern: candidates who clear 63% on at least two of their last three calibrated mock exams pass the live CHP at a rate above the official ABHP 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 CHP in action.
Pick whichever gets you to a yes fastest.
ABHP Part I is offered once a year — fail it and your credential timeline, promotion, and senior HP salary band all slip by twelve months.
Most CHP prep is a stack of decades-old PDFs and a study group Slack; CertPrep gives you a domain-weighted question bank with worked rationale tied to the 2024 ABHP Examination Prep Guide, so every minute of review maps to a real blueprint task.
Common questions
- How is this question bank aligned to the ABHP Part I blueprint?
- Every item is tagged to one of the five official domains and weighted to match the published distribution: 25% Measurements and Instrumentation, 20% Standards and Requirements, 20% Hazards Analysis and Controls, 20% Operations and Procedures, and 15% Fundamentals and Education. Practice exams are drawn in those proportions so your scores predict real exam readiness, not random topic luck.
- Is this enough to pass on its own, or do I still need other resources?
- CertPrep is built as your primary application and recall engine, not a replacement for foundational texts like Cember or the NCRP/ICRP reports the exam cites. Most candidates who pass pair our question bank with one core textbook and the ABHP prospectus. The questions and rationale are where you convert reading into the 63% you need on test day.
- What's the difference between the individual and team plans?
- The individual plan is $109 for full single-user access to the CHP Part I bank, analytics, and timed mock exams. Team plans run $59 per seat and add a manager dashboard for tracking domain-level performance across your RP staff — useful for utility, DOE, and medical physics groups credentialing multiple people in the same exam cycle.
