Praxis test
（重定向自PPST）
A Praxis test is one of a series of American teacher certification exams written and administered by the Educational Testing Service. Various Praxis tests are usually required before, during, and after teacher training courses in the U.S.
In order to be a teacher in most states in the US, the Praxis test is required. It usually consists of two separate tests, Praxis 1 and 2. In some states, alternative teacher certification programs allow prospective educators to obtain licensure without taking Praxis tests.
