question about the SCHOOL GUARANTEE PROGRAM (SGP)

I am trying to get the rate MMS, and my dad who was also a MMS does not want me to enlist unless i can get some kind of school guarantee. My recruiter never told me anything about this program, but i found it in VOL IV of the recruiters manual and when i asked him about it he was rather vague. does anyone know anything about this program it or how to get into it?
