How does a prior service obligation (i.e. ROTC) affect the HPSP obligation?
The service obligations will be served consecutively. For example, a student who had a 4-year ROTC scholarship and accepts a 3-year HPSP will serve for a total of 7 years on active duty. The first 4 years will count towards repaying the ROTC obligation, and the last 3 years count towards repaying the HPSP obligation.
