The mission of the Jefferson PTSA is to provide support to the school's administrators and staff to ensure that all students who attend Jefferson receive the finest in middle level education. Educational aides and enrichment programs are among a few of the items the PTSA provides to enhance the educational opportunities for all students.

PTSA members also serve on school committees, such as Building Council, Social Justice, Parents as Partners, and Eighth Grade Promotion. Parents volunteer as tutors, mentors, and assist teachers by copying and collating materials for classroom use, providing food and arrangements for staff luncheons, Fall Open House and welcoming new 6th grade families into Jefferson each spring.
