George Y. Komure Elementary, Stockton CA

Original Research by School Decision on George Y. Komure Elementary

George Y. Komure Elementary sits on Henry Long Boulevard in Stockton, serving kindergarten through eighth grade as a regular public school within the Manteca Unified School District. That combination of city and district is worth pausing on: the school is geographically in Stockton but belongs to a district headquartered in Manteca, a circumstance that shapes both which district policies apply and which community context surrounds the school day.

The student body is racially diverse, with Hispanic students making up roughly half the enrollment, a substantial Asian student population, and meaningful Black and multiracial shares as well. A very large share of students qualify for free or reduced-price lunch, placing the school clearly among high-poverty settings in California. Data on English learners and students with IEPs were not available in what was provided, so a parent with a child who has specific support needs should ask the school directly about those services.

State testing results from the 2024-25 CAASPP are reported and they are, plainly, low. In English language arts, fewer than one in three students at most grade levels tested at or above proficiency, with the middle school grades performing somewhat better than the upper elementary grades. Math results are weaker still: across most grades, only a small fraction of students reached proficiency, with fourth and fifth grade results among the lowest reported. Science scores from the California Science Test, reported at fifth and eighth grade, follow the same pattern. Against other districts in San Joaquin County, Komure's overall proficiency index places it in the bottom quartile of that county comparison set. A social studies result from well over a decade ago appears in the data but reflects an assessment and school year too distant to be meaningful now. No trend data spanning multiple years was available, so it is not possible to say from this data whether performance is improving, holding steady, or declining. A parent whose primary concern is tested academic outcomes should weigh this picture carefully and may want to ask the school about specific supports and instructional approaches in place.

Because the school stops at eighth grade, there is no graduation rate to report here.

On the district side, Manteca Unified made a concrete change that affects Komure families with children in kindergarten through sixth grade: the district replaced traditional letter grades with standards-based report cards starting in 2024-25. Instead of A through F, parents now see descriptors like "exceeded," "proficient," "approaching," or "beginning" tied to specific grade-level standards. Seventh and eighth graders continue receiving traditional letter grades. This is a permanent shift in how progress is communicated, and families accustomed to letter grades will need to read these reports differently. The district also publicly reports a voter-approved bond measure funding campus modernization, a multi-decade property tax obligation that affects homeowners in the district's boundaries.

The housing market around the school, based on the zip code, sits well below California's statewide median home value but noticeably above the national median, and values have dipped modestly year over year. Rents have moved slightly upward. Estimated monthly mortgage costs at current rates would consume a substantial share of a typical household budget relative to local incomes, and rent-to-income ratios in this area run high. Stockton broadly is more affordable than the Bay Area, which publicly reported sources note continues to draw buyers and commuters into the region.

Stockton itself is a large inland city, a county seat with an agricultural and logistics heritage that remains economically visible today. Transportation and warehousing anchor private employment, and the city's transit system offers bus service across multiple corridors. Walkability varies widely by neighborhood; the area around the school is not described in the data as particularly pedestrian-oriented, and car access is practical. Downtown Stockton has seen recent affordable housing development and some infrastructure investment, though the city's economic challenges are well documented.

Program offerings for Komure specifically were not available in the data provided, so enrichment activities, extracurriculars, or specialized programs are not something that can be characterized here.

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.
