True-the ibr program is available to federal student loan borrowers in both the direct and guaranteed (or ffel) loan programs, and covers most types of federal loans made to students, but not those made to parents (parentplus). to enter ibr, the student must have enough debt relative to his/her income to qualify for a reduced payment. that means it would take more than 15 percent of whatever s/her earn above 150% of poverty level to pay off your loans on a standard 10-year payment plan. because incarcerated students have no source of income and are not actively seeking full time work, s/he is eligible for the ibr program.
