STH,
I have a similar problem whereby my eldest (11 yo) is now starting Year 7 tomorrow with JPA only giving the the low rate where previously he would have received the senior rate. The school's fees reflected the fact that miltary personnel received the higher rate for years 7 and 8.
This has only happened because of the introduction of JPA.
Try and explaining that to JPAC is
Had a chat with those nice people at the Services Children's Education at Upavon who said, according to their data, that our school does qualify for the higher rate in years 7 and 8.
I am now going through the process of getting JPAC to speak to SCE direct.
