Graduate PLUS is a type of federal student aid, in the form of student loans, which is available to graduate and professional students. Similar to the Parent PLUS loan for parents of dependent undergraduate students, the Graduate PLUS loan is an unsubsidized federally guaranteed education loan with no annual or aggregate limits. It has no grace period and it goes into repayment as soon as the funds are disbursed to the borrower. It has the same deferment and forbearance options as the federal Stafford loan program. As such, graduate and professional students can postpone repayment using in-school deferment while enrolled at least half-time in a degree or certificate program of study.
