Loomis Basin Charter, Loomis CA - Test Scores & Data

Original Research by School Decision on Loomis Basin Charter

Loomis Basin Charter is a kindergarten through eighth-grade charter school serving a small enrollment in Loomis, a semi-rural Placer County foothills community marked by large residential lots, horse farms, and a preserved historic downtown. The school is part of Loomis Union Elementary, the parent district.

Academic performance shows solid proficiency in English language arts and moderate strength in math, with notable variation across grades. In language arts, proficiency runs highest in the middle grades (particularly grade six), while math proficiency peaks in grades four and six but dips notably in grades seven and eight. Science proficiency at grade five sits above the midpoint; grade eight science is weaker. When looked at across all tested grades and subjects together, the school's overall proficiency index positions it in the top quartile among Placer County's districts.

The student body is predominantly white, with smaller shares identifying as multiracial, Hispanic, and Asian. A small portion of students qualify for free or reduced-price meals, indicating a relatively affluent enrollment on average. Data on students with disabilities and English learners was not available. The school serves roughly balanced cohorts across its grade span, with slight growth in the upper elementary and middle school grades.

Loomis itself is a slow-growth community with a distinct residential character. Home values in the area are high, placing housing well above the state average; families should expect monthly housing costs to be substantial, whether mortgaged or rented. The downtown core is walkable for daily needs, while most daily life is car-dependent given the rural lot sizes and spread-out layout. Civic life centers on parks, the town library and museum, and transit connections via bus and train.

A material constraint on the school and district is recent. In November 2024, Loomis Union Elementary placed Measure E, a school facilities bond, on the ballot to repair aging buildings, upgrade systems, and improve classroom and laboratory spaces. The measure failed by a narrow margin. Many district buildings are decades old, and the district had not asked voters to support facilities funding in many years. With the bond election lost, families should understand that major facility repairs remain unfunded, and the district continues to operate aging infrastructure.

The school's enrollment is small relative to its grade band, and the setting is genuinely rural in character. It functions as a neighborhood anchor within a town that prizes its small-town identity and preserves its historic fabric while accommodating measured new residential development. For families seeking a K-8 pathway in a tight-knit, semi-rural community with solid academic grounding in language arts, the school offers a clear fit, though the facilities constraint is a real consideration for long-term enrollment stability.

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.
