Jefferson Elementary, Corona CA - Test Scores & Data

Original Research by School Decision on Jefferson Elementary

Jefferson Elementary serves kindergarten through sixth grade in Corona, a suburban city in northwestern Riverside County. The school enrolls a student body that is almost entirely Hispanic, with a substantial share of students qualifying for free or reduced-price lunch. Nearly all students come from low-income households.

The school's California state assessment results in math and English language arts are substantially below the statewide proficiency bar. In math across grades three through six, proficiency ranges from low to mid-range, with sixth grade performing notably higher than third and fourth grades. In English language arts, the picture is similar, though sixth-grade students show stronger performance here, reaching closer to the low-to-mid range; third and fourth graders remain quite low. The school also administered the California Science Test in grade five, where proficiency was low. Across tested subjects and grade levels, the school's overall proficiency index places it in the bottom quartile relative to districts in Riverside County.

The school sits in a community experiencing growth. Corona is a large Inland Empire city that has evolved from its early twentieth-century identity as the center of California's lemon industry into a diverse residential and manufacturing hub. The housing market reflects regional trends: home values and rents are moderately high, though annual home-value changes have been modest. The city is actively investing in downtown revitalization, with nine catalyst projects underway including pedestrian improvements to Sixth Street and new retail and housing. New residential construction continues across master-planned and infill neighborhoods, and the city has approved multiple zone changes to add housing stock.

State assessment data for this elementary school is available through grade six. The school does not have a graduation rate, as it serves only the K-6 grades. Information about special education enrollment, English learner enrollment, chronic absenteeism, and discipline was not available in the data provided. A parent may want to look into the school's programs, staffing, and specific supports directly with the school or district to understand how academic instruction is organized and what targeted interventions exist for students who are not yet proficient.

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.
