Can you get certified medical aide license if only have a GED?

Generally, no. While specific requirements vary by state and even by the specific certifying agency, most Certified Medical Assistant (CMA) programs require a high school diploma or its equivalent (GED) *and* additional coursework or a formal program of study. Having a GED alone is typically insufficient to meet the educational requirements for certification. You'll need to complete a medical assisting program accredited by a recognized body (like the Commission on Accreditation of Allied Health Education Programs (CAAHEP) or the Accrediting Bureau of Health Education Schools (ABHES)).
