Surprising, I've never heard of a school that doesn't actual teach the techniques required to test!
If you don't know the requirements then you are not ready to test. These should be taught to you by your instructor(s) and your fellow students who share the same belt level or higher. Then you should be tested periodically by your instructor(s) to ensure that you know these prior to any permission to test.
These questions you should take back to your school and ask, not on a forum board. Sorry!
