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. The Praxis I, or Pre-Professional Skills Test (PPST), consists of three exams: reading, writing, and mathematics. In most colleges and universities, a passing score must be earned for admission to teacher education.
