Medical assistants do not belong to unions. Membership organizations for medical assistants include the American Association of Medical Assistants (AAMA), American Medical Technologists (AMT), American Society of Podiatric Medical Assistants (ASPMA), and the American Academy of Ophthalmic Professionals (AAOP). The AAMA, AMT, ASPMA, Joint Commission on Allied Health Personnel in Ophthalmology, National Center for Competency Testing, National Healthcareer Association, and the Institute for Credentialing Excellence provide certification. The Accrediting Bureau of Health Education Schools, Commission on Accreditation of Allied Health Education Programs, and the International Council of Accreditation for Allied Ophthalmic Education Programs accredit postsecondary medical assistant training programs.
