About MSSM

We are a STEM (Science, Technology, Engineering and Mathematics) magnet residential high school for scholars in grades 9-12 who enjoy stretching their brains in new and challenging directions. Our students hail from across the state of Maine and around the world. They come for inquiry, camaraderie, and a unique high school experience. Here students, staff, and faculty engage in energetic intellectual sparring served up with encouragement and support.

Why Limestone? Following the 1994 closure of Loring Air Force Base, the Maine State Legislature chartered and funded the Maine School of Science and Mathematics (MSSM) at the site of the Limestone High School. MSSM also acquired the former nearby elementary school and promptly converted it to a 150 bed dormitory. The fall of 2017 saw the first time we hosted our own varsity athletic program independent from the Limestone Eagles, LCS, as they recently merged with Caribou High School. The MSSM Penguins enjoy three varsity level athletic teams in all three seasons, both boys and girls. The inaugural fall season bode well for our scholar-athletes as both soccer teams qualified for the play-offs while several of the cross-country runners advanced to the State meet. In 2022, both boys and girls volleyball teams won All-Aroostook Championship.

Throughout the years, MSSM continues to rank strongly in such publications as US News and World Report ranking as high as number two in the nation in 2019. As a member of the National Consortium of Secondary STEM Schools (NCSSS), MSSM strives to remain current in STEM education.
