Lamar Jr. High is a student-centered school dedicated to every student's opportunity to dream. The faculty and staff believe that education is a joint effort among educators, students, and parents. Parents are strongly encouraged to become involved in their children's academic and extra-curricular activities. Lamar's VIPS (Volunteers In Public School), the Parent Advisory Committee, and the site-based decision team utilize the talents of parents and encourage parents' input into a variety of school related activities.

Classes are ability-grouped with an emphasis placed on higher-order thinking skills. The school day includes seven 50-minute periods and a 25-minute advisory period, which is used for tutoring, study hall, and activities.
