The NASA Explorer Schools Project (NES) establishes a three-year partnership between NASA and school teams, consisting of teachers and education administrators, from diverse communities across the country. Focusing on underserved populations, NES joins educators, students, and families in sustained involvement with NASA's research, discoveries, and missions. The project is designed for education communities at the 4-9 grade levels to help school teams improve teaching and learning in science, technology, engineering, and mathematics through structural (professional development, stipends, grants) and curricular supports based on NASA's resources.
