Which assessment evaluates pedagogical content knowledge for the OSAT?

The Praxis exam is specifically designed to assess the pedagogical content knowledge of prospective educators, making it the correct choice for this question. It evaluates not just general academic skills, but also the specific teaching knowledge and strategies necessary for successful instruction in a classroom setting. The assessment includes various tests that focus on different aspects of teaching, such as content knowledge, professional knowledge, and teaching skills.

In contrast, the ACT and SAT are standardized assessments primarily used for college admissions and assess general academic skills rather than specific pedagogical knowledge. The GRE is aimed at evaluating readiness for graduate-level education and also does not focus on teaching methods or pedagogical content knowledge. Therefore, the Praxis exam stands out as the assessment specifically tailored to evaluate the competencies required for effective teaching.
