High school students should study mathematics, social sciences, health, and business related courses. No matter what area of specialization a student chooses, a bachelor's degree is the minimum requirement. Colleges and universities usually offer bachelor's, master's and doctoral degrees in health administration. One-year programs offering a certificate or diploma in medical office management or health services administration are also available. While a bachelor's degree is satisfactory for entry level positions, a master's degree in the field is considered to be a standard credential depending upon a student's goals and aspirations. One-year of residency in an approved hospital is also required. Upon completion of Health Information Management Program, individuals can earn the designation, Registered health Information Administrator (RHIA) by passing an exam provided by the AHIMA.
