NSF is proposing regulations in consultation with the Secretary of Education to govern the process of converting scholarships to student loans when the scholarship recipients fail to meet their required service obligations under the  Robert Noyce Teacher Scholarship (Noyce) Program. This program provides funding to institutions of higher education to provide scholarships to STEM major undergraduates and professionals to become effective certified K-12 STEM teachers and experienced, exemplary K-12 teachers to become master teacher leaders in high-need school districts. Undergraduate and post-baccalaureate STEM professionals receiving funding through the Scholarships and Stipends Track must teach two years in a high-need school district for each year in which they have received financial support. Post-baccalaureate STEM professionals receiving funding through the NSF Teaching Fellowship Track are supported for one year in obtaining a master’s degree with certification and then must teach for four years in a high-need school district during which time they receive annual salary supplements from the grant funds.  Experienced, exemplary K-12 teachers of mathematics or science in high-need school districts receiving financial support through the Master Teaching Fellowship Track may be supported for one year in obtaining a master’s degree and then receive a salary supplement from grant funds for four years as they continue to teach in a high-need school district. Individuals who already possess a master’s degree can be supported for five years with salary supplements from grant funds as they continue to teach in a high-need school district.
