Clinical Medical Assistant Certification (CMAC)
As a clinical medical assistant, you might have numerous responsibilities in a single day. From maintaining medical records to recording vital signs and drawing blood, this career requires extensive knowledge and a strong understanding of both clinical and administrative duties—with an emphasis on the clinical aspect. Earning your Clinical Medical Assistant Certification (CMAC) can help demonstrate your knowledge and skills, making you a more competitive candidate and boosting a potential employer’s confidence in your education and preparation for this career.
Overview of the CMAC certification
To earn the CMAC certification, you’ll complete a comprehensive exam that tests competencies in professionalism, medical law and ethics, clinical medical assisting and administrative medical assisting.
The CMAC certification is administered by the American Medical Certification Association (AMCA). The AMCA Certification Board, established in 2013, ensures that the AMCA certification programs stay current and adhere to national accreditation standards. “AMCA is headquartered in Fairfield, New Jersey, and was established with the vision of enhancing the allied healthcare industry by providing national certification exams that validate the knowledge and expertise of professionals in this field,” the AMCA states.
According to the AMCA, a CMAC certification validates your knowledge, skills and abilities as a medical assistant. “Certified individuals in the workforce reduce risk and enhance consumer protection and public safety,” the association explains. The certification also helps employers to choose staff who have the skills and competencies needed to excel in the career.
Note: The AMCA used to offer the more generalized Medical Assistant Certification (MAC), but they retired this credential as of Jan. 1, 2025.
CMAC eligibility requirements and routes
The AMCA has detailed eligibility requirements. To hold any AMCA certification, you must be at least 17 years old and have or be in pursuit of a high school diploma or its equivalent. You will also need to agree and adhere to the AMCA Code of Ethics.
Additionally, there are three potential paths that you can take to be eligible for the CMAC certification:

- You will need to provide the name of the exam, the test site name or school you attended, the name of the course you completed and your completion date.
- There is no additional application fee to take the CMAC exam with this option.
Path 2:

Path 3:

AMCA publishes data on the pass rates of past exams. In 2024, the CMAC had a 72% pass rate. In 2023, the pass rate was 69%, while in 2022 it was 58%.

How to prepare for the CMAC exam
Your AMCA exam fee includes several preparation materials:
- Certification program outline
- Exam blueprint
- Study guides in PDF format you can download to prepare for your exam
- Online practice tests, including five attempts per exam. Each practice question includes rationale and feedback to help you learn while getting familiar with the testing platform.
- Quizlet study on-the-go option, including flashcards, games and more, which you can access via an app or website.
How to maintain your certification
You must renew your CMAC certification every two years. “Staying certified contributes to professional development by ensuring certificants stay current in their field and enhance their knowledge and skills through participating in continuing education,” explains the AMCA. The two-year certification period allows you to secure employment, gives you time to gain credits through your employer and ensures you don’t let too much time go without education and exposure to your field.
“The allied healthcare fields are in constant change and all healthcare professionals must stay current with those changes,” says the AMCA. “Education taken outside of the AMCA or through the AMCA are both convenient ways to keep certification current.”
To keep your certification current, you must complete 10 continuing education credits every two years. You can complete those credits online for $158 through AMCA’s Career Advancement Volumes and Career Advancement Certificate Programs. Alternatively, you can submit outside continuing education credits, but they must be reviewed and approved. The outside credits cost $11 per hour.
To renew your certification:
- Submit 10 continuing education credits to be reviewed and approved.
- Once the credits are approved, you can submit the renewal form online through your AMCA account.
- Submit your $15 renewal fee.
If your certification lapses, you can reinstate it within one year for a $25 fee. Once your certification expires for more than one year, you must take the CMAC exam again.
