CHP Exam Dates 2026: Testing Windows, Deadlines & Scheduling

How CHP Exam Scheduling Actually Works

Unlike some certifications that run on a fixed annual calendar, the Certified Health Physicist (CHP) credential from the American Board of Health Physics (ABHP) uses a two-part scheduling structure that reflects the very different nature of its two exams. Part I is delivered on demand through Pearson VUE testing centers, meaning your "exam date" is really whatever date you pick within an open registration window. Part II, by contrast, is a proctored written exam administered on a much more limited schedule tied to the ABHP's annual certification cycle.

If you're new to the process, start with the CHP Requirements 2026: Eligibility, Prerequisites & How to Qualify guide to confirm you meet the education and experience thresholds before you spend time worrying about dates. Scheduling only matters once eligibility is settled.

Part I Testing Windows and Pearson VUE Logistics

Part I is a 150-question, five-option multiple-choice exam delivered in 3 hours at a Pearson VUE test center. Because Pearson VUE operates hundreds of centers on a continuous basis, once your Part I application and registration are approved, you're typically given a testing window of several weeks to months during which you can book any available date and time at a nearby center.

This flexibility is genuinely useful for candidates juggling shift work, travel, or ongoing coursework, but it also creates a common planning mistake: candidates apply for Part I before they've built a real study plan, then find themselves scheduling a date that arrives before they're ready. Before you register, look closely at the CHP Exam Domains 2026: Complete Guide to All 5 Content Areas to gauge how much content you'll need to cover in Measurements and Instrumentation, Standards and Requirements, Hazards Analysis and Controls, Operations and Procedures, and Fundamentals and Education.

Part II Deadlines and the Written Exam Cycle

Part II is a fundamentally different logistical event. It's a 6-hour, closed-reference written exam requiring responses to six core questions plus four of eight specialty problems, and it's administered on a set schedule rather than through rolling Pearson VUE bookings. Because it's given far less frequently than Part I, missing an application deadline can mean waiting a full additional cycle before you get another shot.

Eligibility itself is a gating factor here: Part II generally requires six years of professional health physics experience, including three years of applied experience, along with qualifying education, references, and a radiation protection report. If you're not yet sure whether your experience qualifies, the CHP Requirements 2026 article walks through exactly what counts as applied experience versus general experience.

Application Timeline: Working Backward From Your Target Date

The single biggest scheduling error candidates make is thinking about the exam date first and the application deadline second. The ABHP's process actually runs in reverse: your application has to be submitted, reviewed, and approved before you're even permitted to select a Pearson VUE date (for Part I) or confirmed for the sitting (for Part II).

A practical way to think about this is to work backward:

1. Identify the testing cycle or window you're targeting (e.g., a spring or fall Part I window, or the annual Part II sitting).
2. Subtract the ABHP's stated application review period to find your latest safe submission date.
3. Subtract additional time for gathering references, transcripts, or your radiation protection report if you're applying for Part II.
4. Add a buffer of two to four weeks in case documentation needs to be resubmitted.

This backward-planning approach is especially important for Part II candidates, since the experience and reference documentation takes real time to assemble and can't be rushed the week before a deadline.

Fees, Deadlines, and What Happens if You Miss One

Scheduling and money are tightly linked in the CHP process, since your application fee and registration fee are typically paid at different stages. Missing a deadline doesn't just delay your test date - it can mean forfeiting fees or having to reapply in a later cycle.

For a full walkthrough of every fee, including how the numbers add up across both parts and what recertification costs on top of it, see CHP Certification Cost 2026: Complete Pricing Breakdown. If a fee or deadline is missed, candidates are generally required to reapply for the next available cycle and pay applicable fees again, so mark your calendar with reminders well ahead of each due date rather than relying on memory.

Choosing the Right Testing Window for Your Domains

Because Part I candidates control their own testing date within the approved window, the real strategic question isn't "when is the exam offered" but "when will I have mastered enough of the five domains to sit confidently." The domain weighting matters here:

The Seven-Year Clock Between Part I and Part II

One scheduling detail that trips up otherwise well-prepared candidates: you must pass both Part I and Part II within seven years. This isn't a soft guideline - it's a hard eligibility rule. If you pass Part I early in your career but delay accumulating the six years of experience (including three years of applied experience) needed for Part II eligibility, the clock keeps running regardless of your readiness.

Practically, this means candidates who pass Part I while still building toward Part II eligibility should track their seven-year window from day one, not treat it as a distant concern. If your experience trajectory suggests you'll hit Part II eligibility close to year six or seven, plan your Part II application in the very first cycle you qualify rather than waiting.

Building a Prep Timeline Around Your Test Date

Once you've locked in a realistic Part I date, working backward into a study calendar helps ensure the domain weighting drives your time allocation rather than an arbitrary study order.
