Was the scholarship from the national board, or directly from Det. 538? The HSSP (national) is not tied to any college at all. The HSSP is tied to the cadet and their intended major (tech or non-tech) My guess is you got the ICSP (tied to the det, cadet and major). That means you can only use it at RIT since it is not the national board. Typically, they will tell you that if you accept their ICSP you must remove your name from the national board. You can't hold onto as a backup and wait to see if the national board will also offer you a scholarship. Usually they want an answer within less than a week after offering, more often it could be 3-4 days.
~ Becareful if you throw it back in the pool (i.e., take your chances on the national), Type 1 is very rare. Only 5% of all applicants get one. Avg best sitting is 31+ ACT, 1380 + SAT.
~ Commanders will call it a Type 1 because in a way it is a Type 1. They will not care whether you are in-state or out of state when it comes to covering tuition. Type 2 and 7 takes that into account. Thus, if RIT charges the equivalent in tuition to an IS college (SUNY) student than it is the equivalent of being a Type 7, and not a Type 1. If RIT charges more than the IS tuition, or you are an OOS student, it is equivalent to a Type 1.
~~ Getting in the weeds, but it is important to understand what you may be risking if I am correct and it is a scholarship offered from the det., and not the HSSP.
Hope that helps.
