Original Research by School Decision on Basis San Antonio - Jack Lewis Jr Campus

BASIS SAN ANTONIO - JACK LEWIS JR CAMPUS is a charter middle school serving grades six and seven in north-central San Antonio, part of the BASIS TEXAS network. The school enrolls just over a small grade-band cohort of students, split roughly evenly between sixth and seventh grade. The student body reflects San Antonio's demographic composition, with a substantial plurality identifying as Hispanic, a meaningful share as Asian, smaller shares as Black and white, and a small population of two or more races. Free-or-reduced-price lunch eligibility data was not available.

The campus occupies a newly built setting on the north side of the city in an area where housing costs are modest relative to state benchmarks and home values have remained steady. The surrounding zip code shows median rent well below state average, making the location accessible to families across a range of incomes. San Antonio itself is growing rapidly, with development extending steadily northward into areas like Stone Oak and Alamo Ranch, and the school sits within that development corridor.

Academically, the school shows uneven performance across subjects and grade levels. In English language arts, students score well. Sixth graders show strong proficiency, and seventh graders match that level. Eighth-grade ELA results stand out as especially solid, with the vast majority of tested students meeting or exceeding proficiency. By contrast, mathematics presents a steeper challenge. Sixth-grade math proficiency is solid, but seventh-grade math shows a substantial drop, with proficiency falling to less than half. Eighth-grade math rebounds somewhat but remains below the sixth-grade level. The pattern across tested science and social studies in eighth grade follows a similar trajectory: science proficiency hovers around two-thirds, and social studies sits at just above one-half.

When averaged across all tested subjects, the school's overall proficiency index positions it in the top quartile among Bexar County districts, a meaningful distinction. However, this aggregate masks the subject-specific gaps, particularly in mathematics at the seventh-grade level and the floor performance in eighth-grade social studies. A parent considering this school may want to look into the school's approach to seventh-grade math instruction and why that particular cohort and subject show such a pronounced dip.

Graduation rate and chronic absenteeism data do not apply; the school serves only middle grades, and those metrics are reported for high schools or collected through different mechanisms. Special education and English learner enrollment counts were not disclosed.

The BASIS charter model emphasizes a structured curriculum with an emphasis on core academics and a particular pedagogical approach. Parents selecting this school are typically drawn to the charter framework and its specific academic model rather than to a neighborhood attendance boundary. With a student body of approximately that size, the school maintains a smaller middle-school environment than many traditional district campuses. San Antonio's rapid growth means the north-side location remains an evolving residential area, and the school itself is relatively new to the region.

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.
