Original Research by School Decision on Allegiance Steam Academy - Thrive Fontana District
Allegiance STEAM Academy - Thrive Fontana District is a newly authorized charter district serving kindergarten through eighth grade in San Bernardino County. The school opened in August 2023 as a tuition-free public charter authorized by Fontana Unified School District for a four-year term. It operates under a project-based STEAM instructional model and draws students from across Fontana and surrounding communities without enrollment boundaries.
The school is quite small, with a current enrollment of around two hundred students distributed across its nine grade levels from kindergarten through eighth grade. The student body is predominantly Hispanic, with smaller shares of Black, Asian, White, and multiracial students. The school serves students from across the wider Fontana area rather than a single attendance zone.
In its first two years of operation, the school had no state assessment data available; K-8 charter schools in California often operate with limited state testing reporting because early grades are not tested statewide and middle-grade testing rules vary. The lack of established academic performance metrics means families cannot yet compare this school's proficiency or growth to county or state benchmarks. With such a new program, a parent would want to speak directly with school leadership about how student learning is being measured, what progress looks like in the school's project-based model, and what data the school tracks internally.
For the 2025-2026 school year, the school relocated from a co-located space to the former Birch High School campus, where it now has exclusive use of a much larger facility. This move materially changes what families can expect: the new site includes dedicated STEAM and music laboratories, a gymnasium, and athletic fields. This expansion of physical space and dedicated specialized facilities marks a significant step in the school's development and suggests room for growth beyond its current enrollment.
The school's STEAM focus and project-based pedagogy appeal to families seeking an alternative to traditional classroom structures. Because the school is still in its founding years, parents should understand that they are choosing a school still establishing routines, outcomes data, and a track record. The absence of state test results is expected at this stage and does not signal weakness; it is simply the nature of a newly opened alternative program. However, parents may want to ask the school directly about internal assessments, how it tracks student growth, parent involvement, and what happens as the charter term progresses and external accountability measures begin to take shape.
