What would be a realistic expectation of increase over 10 years post qualification? He is about 40 and would be looking at primary with no special payments due to maths or languages - or possibly secondary RE. (I know this ignores all the problems of getting a training/course place, getting a job etc, but we need first to assess the practicality of dropping from a salary which is enough for us to lose most of our Child Benefit).
