Lexington Elementary, Pomona CA - Test Scores & Data

Original Research by School Decision on Lexington Elementary

Lexington Elementary is a kindergarten-through-eighth-grade school in Pomona serving a densely Spanish-speaking, economically challenged student body with profound gaps in math and English language arts proficiency, especially in the early grades.

The school's enrollment is small, with roughly equal-sized cohorts across grades. Nearly all students qualify for free or reduced-price lunch, and the vast majority identify as Hispanic; fewer than one in twenty students are white, Asian, or Black. This composition reflects the immediate neighborhood and the broader Pomona student population.

State test results paint a stark picture. In third and fourth grade, students show single-digit proficiency rates in both math and English language arts. Fourth-grade math is particularly weak. Proficiency climbs as students advance: by sixth grade, roughly four in ten students meet the math standard; by seventh and eighth grade, around seven in ten do. English language arts gains are slower, reaching about six in ten proficiency by eighth grade. Science proficiency is similarly low, below one in four students at both fifth and eighth grade.

This grade-level pattern is consistent with schools where learning gaps accumulate in early years and then partially narrow in upper grades, either through concentrated intervention, more advanced students being retained upward, or both. The data does not explain which mechanism is at work here.

Overall proficiency across tested grades and subjects sits below the midpoint among schools in Los Angeles County, meaning students here are performing lower than the median of county schools, though the school is not an outlier. The school does not report special-education identification rates or English learner counts, so the proportion of students receiving intensive support services remains unclear.

Lexington sits in a Pomona housing market where median home values are moderate for the region and rents are rising slightly year-over-year. The city is actively adding housing through infill and state-mandated development, with new transit access via the Metro A Line extension that opened in 2025, tying Pomona to Pasadena and downtown Los Angeles. Employment in the area centers on education, healthcare, manufacturing, and retail, anchored by Cal Poly Pomona and regional hospitals.

The district itself is investing in facilities following approval of Measure UU, a bond measure passed in November 2024 that will raise property taxes to fund classroom upgrades, repairs, and removal of health hazards across schools. The district also reached a teacher salary agreement in March 2024 aimed at making compensation more competitive with neighboring districts, a step taken to support recruitment and retention.

Lexington Elementary is not a school of choice within its district, and no specialized programs or magnet offerings are listed. A parent considering this school should understand it serves a neighborhood population with very low early-grade proficiency and substantial economic need, where instruction will focus on foundational skills. The grade-level data suggests the school may be more effective with older students than younger ones. A parent may want to look into the school's literacy and numeracy interventions, retention and promotion practices, and how it supports English learners, since those questions will shape what a given child's experience looks like.

This schoolPomona Unified, same grade

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.
