- The CMAA passing score is 390 on a 500-point scaled system, not a raw percentage.
- Of 135 total questions, only 110 are scored; 25 are unscored pretest items you can't identify.
- Communication and Professionalism and Patient Encounter each carry 21 scored items - the two heaviest domains.
- Since June 1, 2026, PSI delivery uses an embedded calculator with no scratch paper; whiteboards replace it instead.
How the CMAA Passing Score Actually Works
The National Healthcareer Association (NHA) sets the passing score for the Certified Medical Administrative Assistant exam at 390 out of a possible 500 points. That number sits on a scaled scoring system, which is a deliberately different animal from the raw "number correct out of number asked" math most people expect from a certification exam.
Here's the practical version: you will answer 135 total questions in 2 hours and 15 minutes, but only 110 of those are scored. The remaining 25 are unscored pretest items NHA is quietly testing for future versions of the exam. You won't know which 25 are unscored, so every question deserves your full attention as if it counts - because statistically, most of them do.
Why 390/500 Isn't "Just Get 82% Right"
A common mistake candidates make is treating 390/500 as a straight 78% and assuming they need to answer roughly that share of scored items correctly. Scaled scoring doesn't translate one-to-one that way. The 500-point scale exists specifically so that NHA can hold the passing standard constant across different exam forms, even when one form's questions are, on average, slightly harder or easier than another's.
What this means for your prep: stop trying to calculate a magic number of missable questions. Instead, treat every domain as something you need genuine command over, because scaled systems tend to punish shaky performance spread across content areas more than they punish being weak in just one narrow spot. For a full breakdown of how NHA structures the exam's difficulty and what "hard" actually means in practice, see How Hard Is the CMAA Exam? Complete Difficulty Guide 2026.
Key Takeaway
Don't study to a percentage target. Study to competency in all seven domains - the scaled system rewards consistency, not lucky clustering of correct answers in your strongest area.
Scored Items by Domain: Where the Points Live
The current test plan is built on NHA's 2021 job-task analysis, with the updated exam version having launched September 12, 2023. It organizes the 110 scored items across seven domains. If you're deciding where to spend your limited study hours, this table is the single most useful thing in this article.
| Domain | Scored Items | Share of Scored Content |
|---|---|---|
| 1. Foundational Knowledge | 10 | Smallest domain |
| 2. Communication and Professionalism | 21 | Tied largest |
| 3. Medical Law, Ethics, and Compliance | 17 | Third largest |
| 4. Scheduling | 16 | Mid-weight |
| 5. Patient Encounter | 21 | Tied largest |
| 6. Billing and Revenue Cycle | 11 | Second smallest |
| 7. Medical Practice Administrative Procedures and Logistics | 14 | Mid-weight |
Notice that Communication and Professionalism and Patient Encounter tie for the largest share, at 21 scored items each. Together they account for nearly 40% of everything that's scored. If you're only going to deep-study two domains, these are the two. For the full content breakdown of each domain - including specific tasks and knowledge statements NHA expects - see CMAA Exam Domains 2026: Complete Guide to All 7 Content Areas.
Communication and Professionalism (21 items)
Covers how you interact with patients, providers, and coworkers under the practical constraints of a front-office or clinical-administrative setting.
- Professional communication with diverse patient populations
- Workplace conduct and interprofessional collaboration
- Handling sensitive or difficult interactions appropriately
Patient Encounter (21 items)
Covers the administrative side of moving a patient through a visit - check-in, intake documentation support, and coordination with clinical staff.
- Verifying and updating patient demographic and insurance information
- Supporting the flow of a visit from arrival to departure
- Recognizing when a situation requires escalation to clinical staff
What the 135 Questions Look Like
NHA describes the CMAA exam as assessing both knowledge and application - meaning you'll see straightforward recall items alongside scenario-based questions that ask you to apply a concept to a described office situation. A question might describe a patient at check-in with a specific insurance issue and ask what the medical administrative assistant should do next, rather than simply asking you to define a term.
This mixed format is one reason candidates sometimes feel underprepared even after memorizing terminology. Application questions require you to have practiced the reasoning, not just the vocabulary. This is exactly the gap that structured practice testing closes - working through scenario-style questions on our CMAA practice test platform before exam day helps you recognize the pattern of "what is this question really asking" under timed conditions.
Exam Day Mechanics That Affect Your Score
The CMAA exam is delivered as either institutional testing or through PSI, either at a test center or via live remote proctoring. A change that took effect June 1, 2026 is worth knowing before you schedule: PSI-delivered exams now use an embedded on-screen calculator, and scratch paper is no longer provided.
- Remote candidates get a digital whiteboard for calculations and notes.
- Test-center candidates are provided a physical whiteboard instead.
- The embedded calculator applies across the exam, which matters for any billing or scheduling math items you encounter.
None of this changes what the passing score is, but it does change how you should rehearse. If you've been practicing math on scratch paper, switch to whiteboard or on-screen calculator practice well before your test date so the tool itself isn't a distraction. For the full timeline of registration windows and what to expect on scheduling day, check CMAA Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Before You Can Even Sit for a Score
A passing score is only relevant once you're eligible to test. NHA's eligibility path combines a high-school diploma or equivalency (or an eligible provisional route) with qualifying healthcare training or relevant supervised work experience. Work-experience options include one year of relevant experience within the preceding three years, and candidates whose training is five or more years old need qualifying work experience on top of that training. Provisional candidates must complete the secondary-education requirement within 12 months.
If any part of this sounds unclear for your situation, don't guess - a wrong assumption about eligibility can delay your ability to even schedule the exam. The full requirements, including how the provisional and work-experience routes interact, are laid out in CMAA Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Allocating Study Time by Domain Weight
Given that Communication and Professionalism and Patient Encounter together make up 42 of the 110 scored items, your study calendar should reflect that weight instead of splitting time evenly across seven domains. Here's a practical way to sequence a multi-week plan around the actual scoring structure.
Foundational Knowledge + Medical Law, Ethics, and Compliance
- Build the vocabulary and compliance framework everything else depends on
- Cover HIPAA, scope-of-practice, and documentation standards
Communication and Professionalism + Patient Encounter
- Spend the most hours here since these two domains carry 42 of 110 scored items
- Practice scenario questions, not just terminology recall
Scheduling + Medical Practice Administrative Procedures and Logistics
- Work through appointment types, scheduling conflicts, and office workflow scenarios
- Review records management and equipment/supply logistics
Billing and Revenue Cycle + Full Review
- Close the smallest-weighted domain, then take full-length timed practice runs
- Rehearse with an on-screen calculator and whiteboard-style note-taking
This sequencing pairs naturally with a structured resource; if you want the day-by-day version of this plan with more granular tasks, see CMAA Study Guide 2026: How to Pass on Your First Attempt. And if you'd rather see condensed, must-know facts in one sitting before a final review pass, the CMAA Cheat Sheet 2026: One-Page Review of Must-Know Facts is built for exactly that.
Key Takeaway
Spend roughly double the study time on Communication and Professionalism and Patient Encounter compared to Billing and Revenue Cycle - the point values justify it.
After You Pass: What the Score Doesn't Tell You
Hitting 390 gets you certified, but certification isn't permanent by default. CMAA credentials renew every two years, requiring 10 NHA CE credits (equivalent to 20 hours). NHA's optional NHA One program costs $95 annually and includes unlimited CE plus no-additional-charge renewal as long as payments and CE requirements stay current; letting an NHA One payment lapse before renewal bumps the cost to $195 plus CE costs. It's worth deciding on your renewal strategy before you even sit for the initial exam, since CE planning is much easier to manage proactively than reactively.
It's also worth thinking past the score itself to what the credential actually opens up. Employers hiring for front-desk, medical office, and administrative-support roles in clinics and practices commonly look for this credential as a hiring signal.

FAQ: CMAA Passing Score Questions
390 on a 500-point scaled scoring system, set by NHA. It is not a simple percentage of questions answered correctly.
There's no fixed "number correct" because the scoring is scaled across 110 scored items (out of 135 total questions), and scaling can vary slightly by exam form. Focus on mastering all seven domains rather than calculating a raw target.
No. Of the 135 total questions, 110 are scored and 25 are unscored pretest items used by NHA for future exam development. You cannot tell which items are unscored while testing.
Communication and Professionalism and Patient Encounter each contribute 21 scored items - the two largest domains, together representing 42 of the 110 scored items.
Yes. Since June 1, 2026, PSI-delivered CMAA exams use an embedded on-screen calculator and no longer provide scratch paper; remote candidates use a digital whiteboard and test-center candidates use a physical one.
Understanding the mechanics behind the 390/500 passing score won't change how hard the material is, but it changes how you prepare - you're studying to build consistent competency across seven domains, not chasing a percentage. Pair that mindset with domain-weighted practice on our practice test platform and you're preparing the way the scoring system actually rewards.
