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 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.

Some twenty plus years later (we hosted our first reunion, the 20th, in 2016) MSSM continues to prepare its students for admission to the world’s top universities and colleges, and we enjoy a hundred percent placement rate year after year. Although a majority of our graduates enter STEM related fields, all disciplines are being represented. It is fascinating to learn of our alumni’s multi-faceted passions that lead them around the globe but, thankfully, many find their way back to the State of Maine.

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