King Elementary, Stockton CA - Test Scores & Data

Original Research by School Decision on King Elementary

King Elementary serves kindergarten through eighth grade in Stockton, California, as a regular public school within Stockton Unified. The school sits in a neighborhood of the city where the housing market shows modestly valued properties, and the broader community context reflects Stockton's role as a processing and transportation hub in California's San Joaquin Valley, with growing e-logistics employment and a downtown anchor anchored by civic institutions and affordable housing development.

The student body at King is predominantly Hispanic, with a substantial share of students qualifying for free or reduced-price lunch, reflecting the economic profile of the neighborhoods the school serves. The enrollment spans nine grade levels from kindergarten through eighth grade, with relatively even cohorts across the elementary years and somewhat smaller populations in the middle grades.

Academic performance on California's state assessments shows a mixed picture. In English language arts, proficiency rates vary by grade, with stronger performance in the upper middle grades—sixth and eighth graders show proficiency rates approaching or exceeding the midpoint range for the grade—while younger students in grades three and four show lower rates. Math proficiency across all tested grades falls below where the school and its community would want it; no grade level achieves proficiency rates above the midpoint, with the weakest results in grade five. Science testing, available only for grades five and eight, shows similarly low proficiency. These results place King below the midpoint among San Joaquin County districts in overall proficiency across tested subjects and grades.

The school operates within Stockton Unified, a district that has undertaken deliberate curriculum changes aimed at addressing foundational skills. The district adopted SIPPS, a structured phonics program, as its reading approach, crediting it with gains in early-grade reading. This represents the instructional framework now being implemented at King. The district also adopted a 2024-2027 Local Control Accountability Plan centered on equity priorities, including academic achievement, support for students with disabilities, and creating positive learning conditions for Black students. For families in the building, the district began implementing a cell phone policy in the 2025-26 school year, and voters approved Measure C, a bond measure for facility improvements funded through property taxes.

A parent considering King should understand that the school serves a community with high economic need and that state assessment data shows students are struggling with grade-level proficiency, particularly in mathematics. The school is part of a district actively working on reading instruction through SIPPS and equity initiatives, but the current proficiency results suggest these efforts are still taking hold. A parent may want to look into further with the school what additional reading or math support is available, how the SIPPS framework is being implemented in early grades, and what progress the school has seen in the current year compared to these baseline results.

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.
