Original Research by School Decision on Glenbrook Academy
Glenbrook Academy is a small special education school serving grades six through twelve, located in Concord and part of Mt. Diablo Unified. The school enrolls a small number of students, with most attendance concentrated in the high school grades rather than middle school.
The student body is economically diverse but leans toward lower income; a substantial share of students qualify for free or reduced-price lunch. The enrollment reflects a mix of racial and ethnic backgrounds, with roughly equal representation from Hispanic and white students, along with smaller groups of Black students and students of multiple races.
State assessment data for Glenbrook Academy is not available to the public. This is typical for small special education schools, where California suppresses or withholds proficiency results to protect student privacy when enrollment in tested grades falls below a reporting threshold. Because the school serves a specialized population with individualized education plans, state standardized testing measures may also not be the primary lens through which the school or families assess progress. A parent interested in understanding how students perform academically and on functional skill goals would want to ask the school directly about its assessment practices, how it measures student growth, and what outcomes it tracks for its graduates.
The school sits in Concord, a commercial and residential hub in central Contra Costa County. The city is anchored by Todos Santos Plaza downtown, a walkable gathering space with dining, a farmers market, and summer concerts within easy reach of the Concord BART station. Much of the city reflects post-war suburban planning, though downtown is pedestrian-oriented and home to the Contra Costa County Library and Civic Center. Concord's most significant upcoming change is the planned multibillion-dollar redevelopment of the former Naval Weapons Station on the northeast side, expected to add substantial housing and commercial space, though construction timelines remain years away.
Glenbrook Academy serves students with disabilities in a dedicated setting. Because of its specialized mission and small size, families should view this school within its own framework: not as a comparison to traditional public high schools, but as a placement designed for a particular population and set of learning needs. Parents of students with IEPs who are considering or referred to Glenbrook should have direct conversations with the school about the nature of programs offered, the transition and career readiness supports available, graduation pathways, and how the school works with families on long-term planning as students approach adulthood.
