Review Chapter Structure
Tri-M® is composed of Senior and Junior chapters — Senior Division is grade levels 10, 11, and 12 and Junior Division is grade levels 6, 7, and 8.
Ninth grade may be included in either a Senior or Junior chapter depending on the school structure.
Schools with grades 6-12 in one building may house both a Junior and Senior chapter, but both chapters must be registered in order to have all grade levels participate.
