- HTCC sets the passing standard at 75 on a 0-99 scaled-score range, not a raw percentage.
- The exam has 200 multiple-choice items across four domains, with Domain 3 worth 32% of your score.
- HTCC's most recently published pass rate was 58% for Fall 2025 - treat 75 as a real hurdle, not a formality.
- The $500 application fee applies per attempt, so a failed exam has real financial cost.
The Number You Actually Need
If you're preparing for the Hand Therapy Certification Examination, the single number that matters most is 75. That's the passing standard set by the Hand Therapy Certification Commission, Inc. (HTCC) on a scaled-score range of 0 to 99. It is not a raw percentage of the 200 multiple-choice questions on the exam, and it is not the same every administration - which is exactly why so many candidates misunderstand what they're actually being asked to do.
This distinction trips up a lot of otherwise well-prepared occupational and physical therapists. You can't walk into the PSI testing center thinking "I need 150 out of 200 correct" because that math doesn't apply to a scaled-score model. Understanding how HTCC converts your raw performance into that 0-99 scale is the first step toward building a study plan that actually targets the passing line instead of guessing at it.
How the 0-99 Scaled Score Works
Scaled scoring is a statistical adjustment process used by many high-stakes certification boards, and HTCC applies it to the CHT exam to account for slight variations in difficulty between different test forms. Instead of reporting the number of questions you answered correctly out of 200, HTCC converts your raw score into a standardized scale from 0 to 99 using a psychometric formula that accounts for item difficulty.
In practice, this means two candidates who each answer a slightly different mix of questions correctly - one facing a marginally harder form, one an easier form - can both land on the same scaled score of 75 if their underlying competency is equivalent. It also means you should stop trying to reverse-engineer "how many questions can I miss and still pass." HTCC does not publish the raw-to-scaled conversion table, and it can shift slightly between test cycles.
What you can control is your depth of knowledge across all four content domains, because the scaled score reflects overall mastery, not performance on any single section. For a full breakdown of how those domains are weighted and tested, see the CHT Exam Domains 2026: Complete Guide to All 4 Content Areas.
Key Takeaway
Stop counting "safe misses." Focus on broad competency across all four domains, since the scaled score rewards consistent mastery over lucky guessing in any one area.
Passing Score by Domain
HTCC does not report a separate passing score for each domain - the 75 is an overall composite. But because the exam blueprint weights domains unevenly, your preparation time should not be split evenly either. A candidate who is razor-sharp on wound care but shaky on prognosis and plan-of-care reasoning is much more likely to land below 75 than one who is moderately strong across all four areas, simply because of how the 200 questions are distributed.
Domain 1: Assess Upper Limb and Relevant Patient Characteristics - 26%
Roughly 52 of the 200 questions test your ability to evaluate range of motion, sensation, strength, edema, scar tissue, and functional status, while also weighing psychosocial and comorbidity factors that affect treatment.
- Standardized outcome measures and their appropriate application
- Special tests for nerve, tendon, and joint pathology
Domain 2: Determine Prognosis and Individualized Plan of Care - 20%
About 40 questions assess clinical reasoning: turning assessment findings into a realistic, patient-specific treatment trajectory.
- Tissue healing timelines and how they constrain goal-setting
- Prioritizing interventions when multiple diagnoses overlap
Domain 3: Implement Plan of Care and Therapeutic Interventions - 32%
The largest domain, with roughly 64 questions, covers the actual hands-on and modality-based work of hand therapy.
- Orthotic fabrication decisions and material selection
- Therapeutic exercise progression, modalities, and post-surgical protocols
Domain 4: Fundamental Knowledge and Basic Science - 22%
About 44 questions test the anatomical, physiological, and biomechanical foundation everything else is built on.
- Upper extremity anatomy, including vascular and nerve pathways
- Biomechanics of joint loading and tissue response to injury
Because Domain 3 alone represents nearly a third of the exam, it deserves proportionally more of your review hours. Candidates often underestimate this domain because it feels "clinical" and familiar from daily practice - but the exam tests it at a depth and breadth that daily caseload rarely covers on its own.
What Scoring 75 Actually Requires
Because HTCC doesn't publish the raw-score cut point, the honest answer to "how many questions do I need right" is: nobody outside HTCC knows the exact number, and it can move slightly between forms. What is knowable is the level of preparation that reliably produces a 75 or higher - and it's more than passive familiarity with hand therapy concepts.
Candidates who clear the passing standard consistently share a few traits:
- They can apply concepts to scenario-based questions, not just recall definitions - the CHT exam leans heavily on case-style items that require synthesizing assessment data into a decision.
- They've reviewed all four domains deliberately, rather than relying only on what their current clinical setting exposes them to (a hand clinic focused on post-op flexor tendon repairs won't naturally build strength in, say, complex regional pain syndrome management).
- They understand the four-hour, 200-item format well enough that pacing isn't a source of lost points.

Why the Pass Rate Matters Here
HTCC's most recently published pass rate was 58% for the Fall 2025 administration. That figure is worth sitting with: it means a meaningful share of licensed, experienced OTs and PTs - each of whom already met the 4,000-hour direct practice requirement - did not reach the scaled score of 75 on that attempt.
This isn't meant to be discouraging; it's meant to correct a common misconception that the CHT exam is a formality once you've logged your clinical hours. The hour requirement proves you've had exposure to hand therapy practice. It does not, by itself, guarantee you've organized that experience into the structured, testable knowledge the exam demands across all four domains.
Candidates sometimes ask whether the difficulty is worth the outcome given the time and cost involved. If you're weighing that question, Is the CHT Certification Worth It? Complete ROI Analysis 2026 and CHT Salary Guide 2026: Complete Earnings Analysis both address it from different angles.
Registration, Fees, and Retake Mechanics
The financial and logistical structure around the exam is part of why hitting 75 on your first attempt matters so much. HTCC, working with PSI Services for test delivery, charges a $500 application fee. That fee is tied to your attempt, meaning a candidate who scores below 75 and needs to retest is looking at another full application cycle and another $500 - on top of losing months of momentum waiting for the next testing window.
- Testing is offered at PSI centers during defined spring and fall windows each year, not on-demand.
- Eligibility requires a current OT or PT credential in good standing, at least three years licensed or certified, and 4,000 documented hours of direct hand-therapy practice.
- Once certified, renewal happens every five years, either by re-examination or by documenting 2,000 work hours plus 80 professional-development contact hours.

Testing windows and application deadlines are covered in CHT Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Key Takeaway
Because retakes cost another $500 and require waiting for the next spring or fall window, treat your first attempt as the one that counts - over-preparing slightly is cheaper than retesting.
Timing Your Prep Around the Score You Need
Given that Domain 3 carries the most weight and Domain 2 requires the most applied clinical reasoning, a study schedule that treats all four domains equally is wasting hours you don't have to spare. A more efficient structure allocates study blocks roughly proportional to domain weight, with extra time reserved near the end for mixed-domain practice questions that mimic the exam's actual scenario-based format.
Domain 4 Foundation
- Rebuild upper extremity anatomy and biomechanics from the ground up
- This foundation makes Domains 1-3 easier to learn, since assessment and intervention both depend on it
Domain 1 Assessment Skills
- Drill outcome measures, special tests, and evaluation frameworks
- Practice interpreting assessment findings in scenario format, not just memorizing test names
Domain 3 Interventions (largest block)
- Cover orthotic fabrication, modality selection, and post-surgical protocols in depth
- Allocate the most hours here given its 32% weight
Domain 2 Clinical Reasoning
- Practice turning assessment data into prognosis and care-plan decisions
- Focus on prioritization when multiple diagnoses or comorbidities overlap
Full-Length Timed Review
- Take mixed-domain practice sets under four-hour, 200-item conditions
- Review missed items by domain to find where your scaled score is likely weakest

Mistakes That Push Candidates Below 75
A few recurring patterns show up among candidates who score just under the passing standard rather than comfortably above it:
- Over-relying on current caseload experience. If your clinic sees mostly one injury pattern, you may be underexposed to entire subsections of Domain 3 or Domain 1 that the exam still tests broadly.
- Treating the 4,000-hour requirement as preparation. Clinical hours qualify you to sit for the exam; they don't automatically translate into exam-ready recall of terminology, special tests, or biomechanical principles.
- Under-practicing with realistic question formats. The 200-item, scenario-heavy structure rewards familiarity with how HTCC phrases and layers questions - something generic anatomy review doesn't build.
- Ignoring pacing across four hours. Running out of time on the back half of a 200-question exam can turn a passing performance into a near-miss.
Practicing under realistic timed conditions on chtexamprep.com is one of the more direct ways to close this gap before test day, since it mirrors the pacing and question style you'll actually face at the PSI testing center.
FAQ
HTCC sets the passing standard at 75 on a scaled-score range of 0 to 99. This is not the same as answering 75% of the 200 questions correctly, since HTCC applies statistical scaling to account for item difficulty across different test forms.
HTCC does not publish a fixed raw-to-scaled conversion, so there is no reliable "safe number of misses." Because scoring is scaled rather than a simple percentage, the best strategy is building broad competency across all four domains rather than trying to calculate a missable-question threshold.
You will need to reapply and pay another $500 application fee, then wait for the next available spring or fall PSI testing window. Given HTCC's most recently published pass rate of 58% for Fall 2025, this outcome is common enough that first-attempt preparation should be a priority.
The passing standard of 75 itself is fixed by HTCC, but because scoring is scaled rather than raw, the number of correct answers required to reach that 75 can vary slightly between test forms and administrations.
Domain 3, Implement Plan of Care and Therapeutic Interventions, carries the most weight at 32% of the exam, making it the highest-leverage area for study time. However, since the passing score is a composite across all four domains, neglecting Domains 1, 2, or 4 can still pull your overall scaled score below 75.
Understanding exactly what the 75 passing standard means - and how HTCC's scaled scoring, domain weighting, and retake costs interact - turns "I need to study" into a specific, prioritized plan. Pair that plan with realistic timed practice, and you're preparing for the number that actually determines certification, not a guess at one.
