What’s on the CCMA Exam? All Content Domains Explained
The NHA Certified Clinical Medical Assistant (CCMA) exam covers seven content domains: Clinical Patient Care (56%, 84 items), Foundational Knowledge and Basic Science (10%, 15 items), Administrative Assisting (8%, 12 items), Communication and Customer Service (8%, 12 items), Patient Care Coordination and Education (8%, 12 items), Anatomy and Physiology (5.33%, 8 items), and Medical Law and Ethics (4.67%, 7 items). The exam has 180 total questions: 150 scored and 30 unscored pretest items mixed in unmarked, delivered over 3 hours. The item counts come from NHA’s own 2022 CCMA Test Plan, current as of this writing; the percentages are those counts expressed as a share of the 150 scored items. Clinical Patient Care is by far the largest domain, covering hands on skills like vital signs, infection control, phlebotomy, point of care testing, and EKG procedures, so most of the exam tests what a medical assistant does in a clinical setting rather than what they can recall from a textbook.
The 7 CCMA Domains and How Much Each One Counts
NHA builds the CCMA around a 2022 job analysis of practicing clinical medical assistants, which is why the exam leans so heavily toward hands on clinical skill instead of even coverage across topics. The bars below show each domain’s share of the 150 scored items, scaled so the largest domain reads at roughly 90% width.
Clinical Patient Care: What the Largest Domain Actually Tests
Because Clinical Patient Care makes up 84 of the 150 scored items, it is worth breaking down further. NHA’s detailed test plan splits this domain into six subareas: Patient Intake and Vitals (14 items), General Patient Care (28 items), Infection Control and Safety (15 items), Point of Care Testing and Laboratory Procedures (9 items), Phlebotomy (12 items), and EKG and Cardiovascular Testing (6 items). General Patient Care is the single biggest slice, covering the day to day scope of a clinical medical assistant: rooming patients, assisting with exams and minor procedures, wound care, and preparing and administering medications and injections under a provider’s order. Infection Control and Safety is the second biggest subarea, reflecting how much the role depends on consistent standard precautions and safe handling of biohazardous materials.
What the Other Six Domains Cover
Foundational Knowledge and Basic Science (10%) tests medical terminology, basic pharmacology concepts, nutrition, microbiology, and disease processes: the knowledge base that supports clinical reasoning rather than clinical technique itself. Patient Care Coordination and Education, Administrative Assisting, and Communication and Customer Service are tied at 8% each, together making up nearly a quarter of the exam. These domains test scheduling, medical records, insurance and coding basics, patient education, and therapeutic communication, reflecting how much of a medical assistant’s day happens outside a procedure room. Anatomy and Physiology (5.33%) and Medical Law and Ethics (4.67%) are the two smallest domains. Do not read the small Medical Law and Ethics count as a reason to skip the material: in practice, law and ethics concepts like HIPAA and informed consent also show up woven into scenario questions from other domains, so the working knowledge matters beyond the 7 items formally assigned to it.
How These Domains Show Up in Practice
Understanding the weight of each domain matters most when it changes how you study. A study plan that spends equal time on all seven domains will under-prepare you for the exam NHA actually gives, since more than half the scored items sit inside Clinical Patient Care alone. Practicing hands on scenario style questions in vital signs, infection control, phlebotomy, and point of care testing should take up the bulk of your review time, with the smaller domains getting proportionally less. That does not mean skipping Anatomy and Physiology or Medical Law and Ethics; a handful of missed items in a small domain still counts the same as a handful missed in a large one. It means allocating review time in proportion to what the test plan actually weighs, rather than treating every domain as equally likely to appear.

Frequently Asked Questions
How many domains are on the CCMA exam?
Seven: Clinical Patient Care, Foundational Knowledge and Basic Science, Anatomy and Physiology, Patient Care Coordination and Education, Administrative Assisting, Communication and Customer Service, and Medical Law and Ethics.
What is the largest domain on the CCMA exam?
Clinical Patient Care, at 56% of the exam (84 of 150 scored items). It covers vital signs, infection control, phlebotomy, point of care testing, EKG procedures, and general clinical care tasks.
How many questions are on the CCMA exam?
180 total questions: 150 scored and 30 unscored pretest items. The pretest items are mixed in unmarked, so every question should be treated as if it counts.
Does the CCMA exam test administrative and communication skills, or only clinical skills?
Both. Administrative Assisting and Communication and Customer Service each make up 8% of the exam, alongside Patient Care Coordination and Education at another 8%, so a quarter of the exam sits outside pure clinical technique.
