I just had this discussion with one of the budget techs. yesterday who is going to enforce the $950.00 yearly cap. Basically, I pointed her to the HPSP handbook which recites an exception to the $950.00 limit (See Ch. 7, 7-3(f)(3) for the details). However, the Army is still only going to pay $950.00 to the school directly, I will have to get reimbursed the difference by submitting a cost data worksheet (CDW). I have been in the Army long enough to realize that for this policy, the answer you get is dependent on the person processing your paperwork. In the end you will get the cost of your insurance covered (i.e. at the single rate etc.) but you may have to do some calling and fill out paperwork.
Good luck
