At my school if someone really wants to test our sensei will let them. But usually, when you have your time in your name is posted a couple of months before the next test. We usually don't test right away after reaching our time requirement. We usually schedule a private (usually two-four students) with our sensei, where we review the testing requirements and learn what we need to work on. If our sensei doesn't feel we're ready during the private, he will tell us to wait till the next test.
