The Air Force ROTC offers three types of scholarships:
type 1 - Pays full college tuition, most lab fees and $900/year for books. Approximately 5% of four-year scholarship winners will be offered a Type-1 scholarship (mostly in Computer, Electrical and Environmental Engineering).
type 2 - Pays college tuition and most lab fees up to $18,000 and pays $900/year for books. Approximately 10% of four-year scholarship winners will be offered a Type-2 scholarship (mostly in technical fields). If a student attends an institution where the tuition exceeds $18,000, then he/she pays the difference. All three-year scholarships are Type 2.
type 7 - Pays college tuition up to the equivalent of the in-state rate and $900 per year for books.
Air Force ROTC scholarships are not activated until the student enlists in the Obligated Reserve Section of the Air Force Reserve, signs a contract and passes the medical, moral, fitness and physical qualifications for enlistment and contracting. Scholarship benefits are not payable until 45 days after the start of the fall term.
Upon activation, all scholarship cadets receive a nontaxable monthly allowance (stipend) during the academic year. Currently, the monthly stipend is $300 for freshmen, $350 for sophomores, $450 for juniors and $500 for seniors.
