The elementary school is divided into six homeroom groups, each averaging 14 students. First, second and third grade classes meet from 8 a.m. to 2:30 p.m.; and fourth to sixth grade, from 8 a.m. to 3:15 p.m. All classes dismiss at noon on Wednesdays. The homeroom teacher instructs math, science, language arts and social studies. Homeroom classwork is supported by staff specialist instruction in art, instrumental and vocal music, including Orff-Shulwerk, drama, horticulture, computer and science labs, library skills and Spanish. Physical education is offered four days each week, introducing students to a variety of cooperative sports, games and team activities. Outdoor education programs support the child's academic and social growth while providing a vital connection with the environment.

A dedicated elementary/junior high library and resource center provides a comfortable space to enjoy a good book, develop beginning computer research skills, or get extra help with schoolwork. Elementary and junior high students also utilize Oak Grove's fully equipped art facilities, and they showcase dramatic productions on the Pavilion's outdoor stage or the indoor student center.

Small class sizes allow teachers to respond to each student's academic and emotional needs, and closely monitor student progress and well-being. Comprehensive, semiannual written student evaluations are complemented by parent-teacher conferences and monthly parent meetings, giving a complete and accurate picture of the elementary student's academic, social and emotional development. Written grades are issued after the sixth grade, as students begin the natural transition to a college-preparatory high school program.
