This test is not knowledge base. Before registering to take this test, I would ensure that you have taken at least one special education course, and have a solid understanding of what it means to create a culturally responsive lesson. Without these stepping stones of previous exposure, this will be a very difficult test to take. Expect to do a lot of reading on this test and be able to choose what works best for minority students. Being a white male, from a majority white area, I would not have succeeded on this test without a background in culturally responsive lesson planning. Make sure to read up on your theorists before taking this exam as well.
