Well, it may depend on which PRAXIS test you are referring
to...
Praxis tests are standardized tests that many states use in
their teacher licensure and certification processes. There are two
main types of Praxis tests: Praxis I (sometimes referred to as
Praxis 1) and Praxis II. Praxis I, or Pre-Professional Skills Test
(PPST), is utilized in the admissions process for teacher education
programs. Praxis I measures basic academic skills. The Praxis II
tests cover a wide variety of specific content areas. The Praxis II
tests are often required before student teaching begins.
The Praxis I tests are similar in "difficulty" to an ACT or SAT
test. The Praxis II tests vary in difficulty depending on the
subject.
