This is a question to all teachers who have moved interstate, especially across country. I moved from AZ to my hometown of AL. I want to get certified here for the 16-17 school year. Then I plan to move to NY next year. I took the NES tests for Elem. Professional Knowledge and Elem. Subject I & II... but AL uses Praxis tests and I NY uses another test. Do you have to retake your certification tests for every state if they are different?
