The GMAT
The Graduate Management Admission Test is required by most schools of management for their master's degree candidates. These schools usually offer an M.B.A., but for health care purposes, the GMAT is usually required for such programs as hospital administration and may be required for other health care administrators as well.
There are three sections, which cover verbal, quantitative (math), and analytical writing, and may include items such as problem-solving questions, reading comprehension, critical reasoning, and grammar.
