Winston Int of Excellence, San Antonio TX

Original Research by School Decision on Winston Int of Excellence

Winston International of Excellence is a charter school serving grades 3 through 5 located in San Antonio. It is operated as part of Edgewood ISD, a district that has undergone significant restructuring in recent years.

The school serves a small enrollment of about the size typical for its grade band. The student body is predominantly Hispanic, and a very substantial share of students qualify for free or reduced-price lunch, reflecting the neighborhood's economic profile. The school does not report separate counts for special education or English learner populations in the available data.

State testing results show academic performance that is notably low across both math and reading. In math across grades 3 through 5, proficiency rates are in the single digits to low double digits, with fifth-grade students showing slightly higher performance than younger grades. Reading proficiency is similarly weak, with a small subset of students demonstrating proficiency at the state standard. In science, fifth-grade students showed no proficiency on the state assessment. When measured against other schools tested in Bexar County, Winston's overall proficiency index places it in the bottom quartile among its peer schools in the county.

A parent should be aware that Edgewood ISD voted in November 2023 to close Winston Intermediate School of Excellence as part of a broader district restructuring in response to enrollment decline and charter competition. This closure decision reflects the district's effort to adapt its footprint, though it was part of a larger "Rethink. Redesign." process that included difficult choices about where students would attend school going forward. The district has rolled out alternative "Schools of Innovation" models elsewhere, including single-gender leadership campuses and two-way dual language programs as specialized choice options. At the same time, the district has had seven campuses, including schools in the Edgewood system, placed on TEA-required turnaround plans following the 2024-25 state ratings, signaling ongoing academic performance pressure across the district.

The San Antonio housing market in the 78226 zip code where the school is located shows median home values below the state benchmark. The neighborhood is part of the broader southside area of San Antonio, which has seen substantial growth in recent years as the city ranks among the fastest-growing metros in the nation, though housing affordability challenges remain with rent and mortgage costs meaningful relative to local incomes.

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.
