Several student teachers asked me the other day which Praxis tests to take.You take all 3 tests recommended for Intervention Specialists: 1. Special Education, Application of Core Principles,(10352) 2. Special Education, Knowledge-based Core Principles,(20351) and 3. Special Education Principles of Learning and Teaching--choose one of the areas: K-6, 5-9 or 7-12. For persons in the new program, you would choose the grade range of your Content Pedagogy (Early Childhood, Middle, or Adolescent). For the old program, I would suggest either K-6 or 5-9. This imformation is all in room 200 McGuffey. Regarding passage of the tests, if you do not pass any subtest, you must take it again until you do. Hope this helps. Good luck, Dr. Everington
