The scope and objectives of the OSAT (Oklahoma Subject Area Test) and the Praxis tests are different. The Educational Testing Service (ETS) administers a set of tests called the Praxis exams, which are widely regarded and accepted by many US states as a prerequisite for teacher certification. The tests are used to evaluate the knowledge and abilities of aspiring teachers across several grade levels and disciplines. They cover a wide range of academic areas. The Oklahoma Commission for Teacher Preparation, however, is responsible for administering the OSAT, which is unique to the state of Oklahoma (OCTP). The OSAT tests are intended to assess candidates for teacher certification in Oklahoma’s subject-area knowledge and skills. These tests concentrate exclusively on the topics and content that adhere to the academic requirements and curriculum in Oklahoma. Both the Praxis examinations and the OSAT are used as evaluations for teacher certification, although the Praxis exams are more widely accepted and recognized in different states than the OSAT, which is only available in Oklahoma. Individuals hoping to become certified instructors should be aware of the exact exam criteria in their preferred state of certification as the standards for certification may vary between states.
