MSSM is 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 intellec...tual 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 134 bed dormitory. More recently, with the advent of sustainable growth, MSSM opened its second dormitory, affectionately named “the Manor” located downtown and less than half a mile away and is home to 27 students. We have a total capacity of 161 students. In addition to sharing the same roof with Limestone Community School, we also share most of our sports teams.
