MHP Passing Score 2026: Exactly What You Need to Pass

The Passing Standard: Why MHP Doesn't Use a Fixed Cut Score

If you're preparing for the Part II Medical Health Physics examination administered by the American Board of Medical Physics (ABMP), you may be searching for a simple number - "you need 70% to pass" or similar. That number does not exist for this exam, and understanding why is the first real step toward passing it.

ABMP sets its passing standard for MHP through a Modified Angoff process. In practical terms, this means a panel of subject-matter experts reviews every scored item on the exam and estimates how a "minimally competent" candidate - someone who just barely meets the standard to practice safely and independently - would perform on that specific question. Those item-level judgments are aggregated into a cut score for that particular exam form. Because the judgment is applied form-by-form and item-by-item, the raw percentage needed to pass can shift slightly from one testing cycle to the next depending on the difficulty of the specific items used.

For a full breakdown of how ABMP structures the entire credentialing pathway - including Part I, Part III, and the direct-to-oral option for qualified Certified Health Physicists - see our overview of MHP Certification.

What the Pass Rate Numbers Actually Tell You

ABMP has published official Part II pass rates of 44% in 2023, 60% in 2024, and 57% in 2025. These figures are calculated as the number of candidates who passed divided by the number who took that year's exam - not a first-time-only pass rate, and not a rolling average.

The year-over-year swing between 44% and 60% is meaningful. It suggests that outcomes are sensitive to how well-prepared each cohort is for the specific blend of item difficulty that year's Angoff panel set, rather than reflecting a static, predictable bar. A candidate walking in assuming "roughly half fail" without digging into why is missing the more useful insight.

We break down what's likely driving these fluctuations, and how to interpret them against your own preparation timeline, in MHP Pass Rate 2026: What the Data Shows. If you're still deciding whether the credential is worth pursuing given this level of rigor, our ROI analysis lays out the tradeoffs.

How Domain Weighting Shapes Your Path to Passing

Because the passing standard is item-driven, the surest way to influence your own outcome is to master the domains that generate the most items. ABMP's current online blueprint spans nine weighted content areas, and five of them - each carrying 15% - together make up 75% of the entire exam.

Because 75% of the scored content sits in just five areas, a candidate who is strong in Instrumentation but weak in Structural Shielding or Standards and Regulations is taking on far more risk than the reverse.

Question Formats and How They Affect Your Score

The Part II written exam is not a uniform bank of single-best-answer multiple choice. ABMP mixes several formats within the same four-hour session:

• Single-answer multiple choice - the traditional format, one correct response among several distractors.
• Matching - pairing terms, values, or scenarios across two lists.
• Choose-all-that-apply - items where more than one option may be correct, raising the difficulty of partial knowledge.
• Shared-stem Type S questions - a single clinical or technical scenario feeding multiple related items, testing whether you can apply one body of knowledge across several angles.

This mix matters for the passing standard because choose-all-that-apply and shared-stem items are typically judged by the Angoff panel as more demanding - partial recognition of a concept isn't enough. If your preparation has only ever used single-best-answer flashcards, you may be underprepared for how these formats are actually scored. Practicing with formats that mirror this structure, rather than relying solely on recall-based drilling, is one of the more overlooked adjustments candidates can make. Our MHP Study Guide 2026 walks through how to structure practice sessions around this exact mix of formats.

Exam Day Logistics That Influence Performance

The passing standard doesn't exist in a vacuum - exam-day conditions affect how well you can demonstrate what you know. ABMP administers Part II on-site through ExamSoft on the candidate's own compatible computer at a designated venue, so hardware familiarity and software setup are part of your preparation, not an afterthought.

Running the exact ExamSoft configuration on your own machine well before test day, and rehearsing four-hour timed blocks under similar conditions, reduces the number of variables working against you when the actual scoring standard is applied.

The Eligibility Gate Before You Ever See a Question

Passing score questions only matter once you're actually eligible to sit for Part II. ABMP requires a relevant graduate degree, supervised clinical experience that varies by degree and residency pathway, endorsements from both a board-certified physicist and a board-certified physician, and a completed MHP Training and Education Form. Most candidates also need Part I credit or an approved waiver before advancing to Part II, with Part III oral examination following later in the standard sequence. Certified Health Physicists who meet specific qualifications have access to a separate direct-to-oral pathway that bypasses part of this sequence.

These eligibility mechanics affect your passing odds indirectly: candidates who arrive with borderline clinical experience or incomplete endorsement documentation often self-select into testing before they're truly ready. Review every requirement carefully in MHP Requirements 2026: Eligibility, Prerequisites & How to Qualify before setting a target exam date.

Allocating Study Time to the Weighted Domains

Generic study techniques - spaced repetition, timed practice blocks, active recall - all work, but only if they're pointed at the right material. Given that 75% of the blueprint sits in five domains, a simple allocation principle is to spend roughly proportional time to weight, with slightly more buffer on domains where your professional background is thinner.

This is only a skeleton - actual pacing depends on your background and how many prior attempts, if any, you've made. A more detailed, week-by-week framework is available in the MHP Study Guide, and if you're trying to gauge realistically how challenging this exam is relative to your current preparation level, How Hard Is the MHP Exam? Complete Difficulty Guide 2026 is a useful companion read. You can also build exam-day stamina and format familiarity using timed practice sets on our practice test platform.

After You Pass: Maintaining the Credential

Passing Part II isn't the finish line for the credential's requirements - it renews every five years, and maintaining it requires 125 continuing education credits, including at least 65 Category 1 credits, with no more than 60 Category 2 credits counted toward the total. Building recertification planning into your career early, rather than scrambling near the five-year mark, keeps the credential active without last-minute pressure.

For those still evaluating career direction, it's worth understanding who actually hires professionals holding this credential and how it factors into compensation; see MHP Jobs and MHP Salary Guide 2026: Complete Earnings Analysis for that context, and MHP Training for how formal training programs typically feed into eligibility.
