Caliber: Changemakers Academy, Vallejo CA

Original Research by School Decision on Caliber: Changemakers Academy

Caliber: ChangeMakers Academy is a charter school in Vallejo that serves kindergarten through eighth grade, with an enrollment of about a thousand students. The student body is predominantly Hispanic and Black, with a substantial share from low-income households. The school is embedded in a mid-sized waterfront city that has long been anchored by manufacturing, healthcare, and maritime activity, and that is now being reshaped by redevelopment of the former Mare Island naval shipyard, which closed decades ago. That development could bring significant housing and population growth to the area over the next several years.

The school's academic performance, measured on California state assessments in math and English language arts, sits above the midpoint among the districts in Solano County but remains below where most schools aim. In math, proficiency is notably low across all tested grades, hovering in the low-to-mid range across third through eighth grade. English language arts results are somewhat stronger; proficiency in grades six through eight climbs into the low-to-mid range, while lower grades lag. Science proficiency at grades five and eight is comparable to math performance. The early grades (kindergarten through second) are not tested under California's state assessment, so their growth goes unmeasured by these metrics.

The school draws a student population with high rates of economic need. The absence of English learner and special education enrollment data means a parent should ask the school directly about support for multilingual students and students with disabilities, as these figures are not publicly reported here. The school's name and structure emphasize civic engagement and social change; the specifics of that pedagogy and what course offerings or enrichment programs exist are not detailed in the available data, so a prospective family would want to explore those directly with the school.

Vallejo itself sits about a half hour from San Francisco and Oakland. The city has a walkable downtown core with historic architecture, a waterfront with parks and ferry service to San Francisco, and diverse economic anchors that include Kaiser Permanente, Six Flags Discovery Kingdom, and growing modular homebuilding. Housing is below California's state median price and has declined modestly in the past year, while rents have held relatively flat. The broader economic climate includes moderate unemployment and an evolving labor market. The redevelopment of Mare Island represents a long-term infrastructure and housing project that could shape Vallejo's next generation of residents and demand for schools.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
