MSTHS students participate in a wide variety of extracurricular activities including Student Council, New Hampshire Honor Society, Yearbook, Interact Club (Junior Rotary), CTSO's and more. If a student wishes to participate in sports they do so at the high school in their area of the city. Band and Chorus participation is rare due to extreme difficulty with scheduling.

Throughout the year, MST students enjoy activities and programs hosted by our various clubs and organizations. These invents include dances, tutoring sessions, Walk Against Hunger, bake sales, cookouts and much more.
