MHP Requirements 2026: Eligibility, Prerequisites & How to Qualify

MHP Certification Overview

Certification in Medical Health Physics is administered by the American Board of Medical Physics (ABMP) and validates that a physicist has the clinical knowledge and judgment to practice safely in radiation-intensive healthcare environments. This article focuses specifically on eligibility for the Part II written Medical Health Physics specialty examination - not the Part I General Medical Physics exam and not the Part III oral examination. If you're still deciding whether this credential fits your career, start with What Is MHP Certification? or the broader overview at MHP Certification.

Before you invest time preparing for content, it pays to understand exactly who qualifies, what documentation ABMP expects, and how the eligibility pathway connects to the rest of the certification sequence. Getting this wrong - submitting an incomplete Training and Education Form, missing an endorsement, or misunderstanding your experience requirement - can delay your exam date by months.

Core Eligibility Requirements

To sit for the Part II Medical Health Physics examination, candidates generally must satisfy four categories of requirements simultaneously:

• A relevant graduate degree in medical physics or a closely related field
• Supervised clinical experience, with the required duration depending on your degree type and whether you completed a residency
• An endorsement from a board-certified physicist
• An endorsement from a board-certified physician

In addition, ABMP requires completion of the MHP Training and Education Form, which documents your academic background, clinical rotations, and supervised hours in a standardized format the board can verify. This form is not a formality - it is the primary mechanism ABMP uses to confirm you meet the experience threshold before approving your application.

Education and Degree Prerequisites

ABMP expects candidates to hold a graduate-level degree with substantive coursework in medical physics, radiological physics, or a directly related discipline. The exact experience requirement that follows your degree is degree-dependent: candidates with different academic backgrounds and residency status face different supervised experience thresholds, which is why ABMP publishes a dedicated professional experience requirements document rather than a single blanket rule.

If your graduate training did not include a formal clinical residency, expect to accumulate supervised experience over a longer period under direct oversight of a qualified mentor. If you completed an accredited residency, your pathway to eligibility is typically more streamlined because the residency itself satisfies much of the supervised-practice expectation.

Supervised Clinical Experience

The supervised clinical experience requirement exists because Part II tests applied clinical judgment, not just textbook physics. Candidates are expected to have hands-on exposure to the same domains tested on the exam - shielding design reviews, regulatory compliance work, oncology physics support, diagnostic imaging quality assurance, and nuclear medicine dosimetry - before they sit for certification.

This is also why the exam itself leans heavily on scenario-based and shared-stem "Type S" questions rather than pure recall: ABMP is verifying that clinical exposure translated into applied competence. Candidates who pursue certification without adequate hands-on time in these areas tend to struggle regardless of how much they've studied from books alone - a pattern explored further in How Hard Is the MHP Exam? Complete Difficulty Guide 2026.

Endorsements and the Training Form

Two signed endorsements are required as part of your application package:

• A board-certified physicist who can attest to your technical competence and clinical readiness
• A board-certified physician who can attest to your clinical judgment in a healthcare delivery context

Both endorsers should be familiar with your day-to-day work, not simply acquaintances willing to sign a form. ABMP uses these endorsements alongside the MHP Training and Education Form to build a complete picture of your readiness before you're cleared to register for Part II.

Because the Training and Education Form requires detailed documentation of your degree program and supervised hours, it's worth completing a draft of this form well before your target exam window opens. Reviewing your documentation early also gives you time to fill gaps in clinical exposure across underrepresented domains, such as Non-ionizing Radiation or Laboratory Design, before you finalize your application.

The Part I, II, III Sequence

The standard certification sequence runs through three stages:

1. Part I - general medical physics knowledge, or an approved waiver for candidates who qualify for one
2. Part II - the Medical Health Physics specialty written exam covered throughout this site
3. Part III - the oral examination that follows successful completion of the written stages

There is also a separate pathway: qualified Certified Health Physicists (CHPs) may be eligible to move directly to the oral examination rather than completing the full written sequence. If you already hold CHP status, it's worth confirming with ABMP whether this direct-to-oral route applies to your situation before you invest time preparing for Part II content.

Registration, Format, and Fees

Once your eligibility documentation is approved, registration for Part II involves a few concrete mechanics worth planning around:

• Fee: $690 by check or $715 through PayPal for the 2026 administration
• Format: Delivered on site through ExamSoft on your own compatible computer at a designated testing venue
• Duration: Four hours
• Question types: Single-answer multiple choice, matching, choose-all-that-apply, and shared-stem "Type S" questions
• Materials allowed: Nonprogrammable scientific calculators and scratch paper supplied at the venue

Because you bring your own computer, it's worth verifying ExamSoft compatibility well ahead of your appointment rather than discovering a technical issue on test day.

What the Part II Blueprint Covers

Once you're eligible, your preparation should map directly onto the nine weighted areas in ABMP's current online blueprint (most recently detailed in the information booklet revised May 2025). Five domains together make up 75% of the exam:

The remaining four domains - Instrumentation (10%), Laboratory Design (5%), Radiation Biology (5%), and Non-ionizing Radiation (5%) - round out the blueprint at lower individual weights but still require solid baseline knowledge. For a full walkthrough of all nine areas with study emphasis guidance, see MHP Exam Domains 2026: Complete Guide to All 9 Content Areas.

Preparing Once You Qualify

Meeting eligibility requirements is the entry point, not the finish line. Once your application is approved and you have a confirmed exam date, allocate your remaining preparation weeks according to blueprint weight rather than personal comfort with a topic.

Rotating through spaced review of weaker domains in the final two weeks, rather than cramming any single area, tends to serve candidates better given how the exam mixes question formats across topics. For a structured walkthrough of this approach tailored to Part II, see MHP Study Guide 2026: How to Pass on Your First Attempt, and benchmark your readiness against real numbers in MHP Pass Rate 2026: What the Data Shows. Practicing under realistic timed conditions on our practice test platform can help you get comfortable with the shared-stem format before test day.

Recertification Requirements

Certification in Medical Health Physics is not a one-time credential. It renews every five years, and maintaining it requires accumulating 125 continuing education (CE) credits during that cycle, with at least 65 Category 1 credits and no more than 60 Category 2 credits. Planning your CE activity across the full five-year window - rather than scrambling near the renewal deadline - makes it far easier to meet the Category 1 minimum.
