Federal law requires that nursing aides who work in a nursing home earn the CNA designation by completing at least 75 hours of education and passing an exam. Each state sets its own educational requirements for CNAs that must meet or exceed federal guidelines. CMAs may be trained on the job, or they can complete a formal training program. CMA certificate programs take about nine months to complete and associate degree programs require two years of full-time study.
Both community colleges and vocational schools offer CNA and CMA training. Some nursing homes also offer approved CNA training programs. Several professional associations accredit medical assisting programs; individuals who complete the program are eligible for certification through that organization.
Both federal and state regulations require that CNAs working in nursing homes register with their state's CNA registry. Some states license CMAs, while others require CMAs who perform specific medical procedures to be certified by a recognized medical assistant professional association.
