Original Research by School Decision on Trona High
Trona High is a small, rural public school serving grades seven through twelve in Trona, California, an unincorporated desert community in San Bernardino County. It is the sole secondary school for the Trona Joint Unified School District, and for families considering it, the school, the town, and the district are inseparable.
The most immediate thing to know about the physical setting is that the school moved into a brand-new campus in early 2026. The original buildings were structurally compromised by the Ridgecrest earthquake sequence of 2019, and for years students worked out of temporary spaces at the neighboring elementary school or outdoors. The reconstructed campus, which publicly opened in January 2026 following a groundbreaking in late 2023, includes modern classrooms, science labs, an art lab, a gymnasium, a library and media center, a weight room, and shop facilities. For a community that spent years without a proper high school building, this is a genuine and lasting change.
The academic picture is more difficult. California's state assessments show proficiency rates in math and English language arts that are very low in both seventh and eighth grade, and the overall proficiency index places Trona High in the bottom quartile relative to districts across San Bernardino County. Science scores at the eighth-grade level follow a similar pattern. The trend data covers only the most recent year, so it is not possible to say whether scores are improving, holding, or falling. No graduation rate data was available in this dataset, and chronic absenteeism data was also absent. A parent who wants a fuller picture of outcomes across the high school grades should ask the district directly, since the state testing data here covers only the middle school grades tested under California's system. No information on AP courses, dual enrollment, or career technical pathways was available in the data provided.
The school is very small. Enrollment spans all six grade levels from seventh through twelfth, with the total headcount in the range that fits a single grade cohort at a mid-sized suburban school. A substantial majority of students qualify for free or reduced-price lunch. The student body is predominantly white with Hispanic students making up a meaningful share and smaller numbers of Black students and students of two or more races. Data on English learners and students with IEPs was not reported.
The town itself is remote. Trona sits in a dry lake basin west of Death Valley, built originally as a company town around mineral extraction, and Searles Valley Minerals has long been the anchor employer. In early 2026, publicly reported sources confirmed that the company announced the permanent layoff of roughly half its workforce, effective April 2026, citing market, cost, and regulatory pressures. For a community that has already seen sharp population decline from a mid-century peak, with aging housing stock, high vacancy rates, and many abandoned homes, this is a serious economic blow. Services have gradually shifted to Ridgecrest, the nearest city, and Trona itself has a branch library, a senior center, churches, and the schools as its primary civic institutions. There is no regular bus service; a weekly shuttle to Ridgecrest is coordinated through the senior center. Recreation amenities are limited, and community plans identify a park and youth programming as aspirations rather than current assets.
Housing costs here are far below California's statewide median and well below the national median as well, reflecting the community's economic position. Homes have appreciated modestly in the past year, though from a very low base.
For a family weighing this school: the new campus is a real improvement after years of difficult conditions, and the community has a tight identity rooted in its industrial history. The academic proficiency data, where available, shows outcomes well below state norms, and a parent should have a direct conversation with the school about what supports exist for students across all grades and what the post-graduation picture looks like for its seniors. The broader community context, including the recent mass layoffs at the town's only major employer, will shape the environment students grow up in in ways that go beyond what any school data can capture.
