You are correct, Wally MK 2, it is the same with all educational courses.
You can ONLY claim it if it has a direct relevance to your role in that tax year. For example, if you want to educate yourself in any manner, it cannot be 'in the hope of a better job' it has to be to help you in your current role.
I guess this stops people doing course after course and claiming it back.
I hit this wall a few years ago!
