Julius L Matthey Middle, San Antonio TX

Original Research by School Decision on Julius L Matthey Middle

Julius L Matthey Middle is a regular public middle school serving grades 6 through 8 in San Antonio's south side, in Southside ISD. The school enrolls a small-to-mid-sized cohort of about that size spread evenly across its three grade bands.

The student body is overwhelmingly Hispanic, with a substantial share qualifying for free or reduced-price lunch. English learner and special education enrollment counts were not available in the data provided.

On state testing, Matthey's performance sits above the midpoint among Bexar County's districts on overall proficiency, though the absolute numbers reflect academic ground that needs covering. In English language arts, seventh-grade students outperformed other grades, with a measurable share meeting or exceeding grade-level standards. Sixth-grade math proficiency was the school's lowest point, though seventh-grade math improved. Eighth graders showed modest proficiency on science and notably weaker results on social studies, where only a small minority of students met the standard. The data shows only one year of results, so trajectory over time cannot be assessed.

Matthey sits within a district that made an intentional, lasting shift to phonics-based instruction aligned with the science of reading around the pandemic period. That curricular choice was paired with consistent classroom application across all grade levels, and the district has publicly reported being among a handful of Texas districts to improve test scores during the pandemic years despite serving a high-poverty population. For families considering Matthey, that context speaks to a deliberate instructional approach at the district level.

The school is located in south San Antonio, an area experiencing steady residential growth with newer subdivisions. The housing market in the area is relatively affordable compared to regional benchmarks. San Antonio itself is among the fastest-growing U.S. cities, with substantial new residential and commercial development across multiple neighborhoods.

State test data participation rates were not available, and no information was found on staffing, course breadth, specialized programs, or discipline climate. A parent may want to look into these areas directly with the school to understand the full picture of daily life and support structures available.

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.
