Final answer:
A certified medical assistant needs to recertify the CMA credential every 60 months, or five years, through re-taking the certification exam or completing continuing education credits.
Step-by-step explanation:
A certified medical assistant must recertify the CMA credential every 60 months or five years. The American Association of Medical Assistants (AAMA) requires that to maintain the certification, the individual must either re-take the certification exam or complete continuing education credits. To ensure that medical assistants remain current with the evolving medical field, regular recertification is necessary. Recertifying also reaffirms the assistant's commitment to the profession and ensures that they solve completely any challenges that may come with changes in medical practice and technology.
