Eastside Elementary, Lancaster CA

Original Research by School Decision on Eastside Elementary

Eastside Elementary serves kindergarten through sixth grade in Lancaster, a mid-sized charter city in the high-desert Antelope Valley. The school sits within Eastside Union Elementary District, which recently passed a local bond measure to upgrade aging facilities across its portfolio of schools.

The school's enrollment is small, at roughly mid-range for its grade span, with a notably high concentration of students from low-income households and a student body that is predominantly Latino, with smaller populations of Black and White students and very few Asian students. The district does not report counts for special education or English learner status, so a parent cannot see those breakdowns from the available data.

State testing results show proficiency that lags substantially. In English language arts across grades three through six, proficiency hovers around one quarter of students. In math, proficiency sits a few points lower, at roughly one quarter as well. Science proficiency, measured in grade five, drops to roughly one tenth. These results place Eastside Elementary in the bottom quartile among the schools in Los Angeles County when proficiency is measured across all tested grades and subjects. A parent should understand that this school's academic attainment is a genuine area of need. The school has only one year of data available, so trend direction cannot yet be assessed.

Lancaster itself is a growing city with a defined downtown centered on The BLVD, a redeveloped streetscape with civic institutions, cultural offerings, and mixed-use retail. The broader area is car-oriented desert development. The Antelope Valley economy is anchored by aerospace and defense, healthcare, education, and retail. Housing in the zip code is moderately affordable relative to state benchmarks, though mortgage and rental costs consume a substantial portion of household income. The region is positioned for growth, with industrial and residential development in the pipeline and expanding rail service planned.

The Eastside Union district's approved bond measure will fund long-term facility upgrades to classrooms, labs, technology infrastructure, safety systems, and disability access across its schools, without raising the current property-tax rate. For families considering this school, the academic data is the primary signal: this is a school where the majority of students are not meeting state proficiency benchmarks. A parent may want to discuss with the school and district what instructional supports, intervention resources, and learning strategies are in place, and whether Eastside Elementary would be the right fit for their child's needs.

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.
