I'm not sure how you have gone about this. Teachers only get a pay rise in September in the sense of moving up the pay scale. If you mean you applied for threshold and have been unsuccessful there is an appeals process, where you will need the evidence to prove you should have passed. Other than that pay rises tend to be on length of service. But if you don't have evidence to back up your case, I can't see that you will win. Or at least you will find it very tricky.
