NHA CCMA exam: what's on it and how it is scored

The NHA Certified Clinical Medical Assistant (CCMA) exam is the certification most medical assisting programs point their students at. This post sticks to what NHA publishes in its CCMA test plan (based on a 2022 job analysis, and still the only plan NHA links as of 2026) and its candidate handbook. It leaves out anything NHA does not state publicly, including fees. If you want the companion piece on the number itself, read the CCMA passing score and score report, explained.

The format

The exam has 150 scored items plus 30 pretest items, 180 in total, with 3 hours to finish. Pretest items are trial questions NHA is evaluating. They are mixed in, you cannot tell which is which, and they do not count toward your score. So 30 of the questions you answer are not graded, and you will not know which ones.

A few handbook rules worth knowing before test day:

• The exam runs in one continuous session. No reference materials or personal devices are allowed, but you may use the built-in exam calculator.
• In a live remote proctored session there are no breaks. At an in-person site, a break is allowed but the clock keeps running.
• The exam is in English only, and interpreters are not permitted.
• NHA certifications are accredited by the NCCA (the National Commission for Certifying Agencies, part of the Institute for Credentialing Excellence).

Items can test straight recall or ask you to think through a task, usually framed as a short scenario: a patient presents with something, and the medical assistant should do what first. If you want a feel for the mix, the exam pass score calculator lets you set 150 items and a target and see how many you can miss on a practice set.

The seven domains

Clinical Patient Care is more than half the exam on its own. It is split into six subdomains, each with its own item count:

General Patient Care, at 28 items, is the single biggest block on the test. It is also the broadest, which matters when you plan your study time; see how to study for the NHA CCMA exam for a week-by-week split that follows these weights.

What each domain covers

Foundational Knowledge and Basic Science (15 items) bundles five smaller topics: health care systems and settings (the MA's scope of practice, provider credentials, licensure versus certification, delivery models like the patient-centered medical home and accountable care organizations, payment models), medical terminology (abbreviations, The Joint Commission "Do Not Use" list, word building, lay versus medical terms, directional terms), basic pharmacology (drug classes, controlled substance schedules, side effects versus adverse effects, routes, the rights of medication administration, storage and disposal), nutrition and psychology (nutrients and food labels, therapeutic diets, eating disorders, developmental stages, common mental health conditions, defense mechanisms, stages of grief). If terminology is a weak spot, how to learn medical terminology fast is a good primer, and the controlled substance schedules are the same ones covered in DEA controlled substance schedules for the PTCE.

Anatomy and Physiology (8 items) covers cell structure, anatomical positions and body cavities, the structure and function of major body systems, homeostasis, and the signs, etiology, diagnostics and risk factors of common diseases, plus epidemics and pandemics.

Patient Intake and Vitals (14 items) is patient identification and safety, the medical, surgical, family and social history, screenings and mental health tools, and the vital signs themselves: blood pressure and orthostatics, pulse, respirations, pulse oximetry, temperature by route, pain scales, menstrual status, factors that change vitals, unit conversions, height, weight, BMI and growth charts. Two posts drill the numbers: vital signs normal ranges for the CCMA and blood pressure categories explained.

General Patient Care (28 items) runs from exam room preparation and sterile fields through positioning and draping, instruments for general and specialty exams, non-parenteral and parenteral medication administration (excluding IV), injection logs, suture and staple removal, eye and ear irrigation, first aid and wound care, emergency response and CPR, assisting with minor surgery, discharge instructions, prescription transmission rules, EHR documentation, computerized order entry and telehealth visits. The injection piece is covered in injection angles, needle gauges and sites and the emergency piece in CPR and first aid for the CCMA.

Infection Control and Safety (15 items) is the chain of infection, standard and transmission-based precautions, hand hygiene, PPE donning and doffing, medical and surgical asepsis, cleaning order, sterilization and the autoclave, OSHA bloodborne pathogen rules, sharps and biohazard disposal, post-exposure steps and eyewash, Safety Data Sheets and equipment logs. Start with the chain of infection and medical asepsis.

Point of Care Testing and Laboratory Procedures (9 items) covers non-blood specimens, CLIA-waived testing and its regulations, quality control, in-range and out-of-range values, requisitions and labeling, vision and hearing tests, allergy testing, spirometry and peak flow, and specimen transport and chain of custody.

Phlebotomy (12 items) is a compact version of the NHA CPT test plan: blood components, patient preparation and identification, site selection, tubes and additives, the order of draw, evacuated tube, syringe and butterfly methods, capillary puncture, complications, processing and transport. The sequence itself is in the order of draw, explained, and CCMA vs CPT compares the two exams if you are weighing both.

EKG and Cardiovascular Testing (6 items) covers patient preparation, lead types and electrode placement, artifacts and troubleshooting, recognizing abnormal or emergent tracings versus artifact, Holter and event monitors, stress tests, calibration and transmitting results.

Patient Care Coordination and Education (12 items) is preventive screenings and timelines, clinical quality measures, education methods such as teach-back, nutrition and medication education, community resources, referrals and transitions of care, barriers to care, team-based care, and communicable disease prevention education.

Administrative Assisting (12 items) is scheduling and appointment types, triage for appointment urgency, check-in and check-out, practice management software, medical record sections, mail and faxes, inventory and equipment logs, insurance verification, prior authorizations, diagnostic and procedural coding concepts, billing and the Advance Beneficiary Notice, payment posting, aging reports and appeals, and government regulations such as MACRA.

Communication and Customer Service (12 items) covers cultural and religious considerations, gender identity and pronouns, communication barriers, the communication cycle and therapeutic communication, interviewing, telephone and email etiquette, difficult patients and conflict resolution, escalation and incident reports, and professionalism.

Medical Law and Ethics (7 items) is the smallest domain: HIPAA and related laws, the Patient's Bill of Rights, informed and implied consent, advance directives, power of attorney and guardianship, records retention, criminal versus civil law and malpractice, release of information, and mandatory reporting. See HIPAA and patient consent for medical assistants.

Scoring in one section

Scores are reported on a scale of 200 to 500, and 390 or higher passes. That is a scaled score, not a percent and not a raw count of correct answers, so "390 out of 500" does not mean 78% correct. The cut score is the same on every form of the exam. Your report shows pass or fail plus a rating of Above, Near or Below the passing standard for each domain. If you test at your school you get preliminary results right away; at a PSI center or through remote proctoring, results arrive within 48 hours.

Eligibility, the 30-day retake wait and the two-year renewal cycle are covered in CCMA eligibility, retakes and renewal.

How to prepare

Put roughly half your time into the clinical units, because that is where the items are, and treat the small domains as cheap points you should not give away. The free NHA CCMA exam prep course has 20 units, 159 chapters and 2,272 study cards, built on the 2022 NHA CCMA test plan, with one unit per test-plan domain or subdomain. Work a set of CCMA practice questions once you have been through a unit, since quizzing beats rereading for exactly this kind of applied recall. Encodr is a study aid, not clinical guidance: the provider, facility policy, state law and your own training decide what you actually do in practice.
