Granger School, Granger TX - Test Scores & Data

Original Research by School Decision on Granger School

Granger School serves kindergarten through twelfth grade in a single building located in Granger, a small rural-blackland-prairie town in northeastern Williamson County with deep Czech-American heritage and a historic downtown. The school enrolls roughly a fifth of the students you might find in a mid-sized district campus, drawn from a community where a substantial share of families qualify for free or reduced-price lunch and where about half the students are white and about half are Hispanic.

The most striking aspect of the school's testing profile is a sharp divide between reading and mathematics. In English language arts, students show real strength in eighth grade, with a clear majority meeting proficiency standards; results climb steadily through sixth and seventh grade, and even in the elementary grades fourth and fifth graders show solid mid-range performance. Mathematics tells a different story. Proficiency rates in math across all tested grades sit in the low-to-mid range, with no grade cresting above a point many districts would consider adequate. Science and social studies results, where data exist, also show modest proficiency rates in eighth grade. Across all tested subjects, the school's overall proficiency index places it below the midpoint among Williamson County's districts.

The pattern in English language arts suggests reading instruction is working for older students, and that shift upward by eighth grade points to something the school may be doing well in the upper grades. A parent interested in reading performance might look into this further with the school. By contrast, the consistently lower math proficiency across the entire grade span, from early elementary through middle school, is a structural pattern rather than a grade-level anomaly. This kind of profile often reflects either systemic instructional gaps in math pedagogy or a mismatch between curriculum and student readiness, and it persists across younger and older students alike.

The school operates within a district experiencing rapid change. In 2022, voters approved a substantial bond to address growth, and the district has stated it expects to at least double its student population within a timeframe measured in years. In early 2026, a new secondary school opened on land east of downtown, serving grades 7 through 12 and drawing secondary students away from the original K-12 building. The opening of that new facility directly reshapes what Granger School now is: students here are now primarily kindergarten through sixth grade, with sixth grade likely in transition. This means the school's current profile is in flux. The eighth-grade English proficiency result in the data comes from students who were in the building before the secondary school opened; current and future cohorts may experience different instruction and peer grouping.

State testing data do not provide a graduation rate because the school no longer serves high school students. The district has not publicly reported attendance, chronic absenteeism, or special-education and English-learner counts in the available record, so those details are not available here.

The housing market around Granger reflects regional expansion pressure from the Samsung semiconductor plant and broader Williamson County growth, with median home values in the area below the state benchmark and affordability marked by price-to-income ratios and rental costs that suggest moderate strain for many households. Most families own their homes. The town's economy locally is small, with the school district itself named as a major employer.

For families in Granger, this school represents the local option for elementary and lower-middle-grades instruction. The strength in eighth-grade reading is worth noting; the persistent math gap is worth understanding by talking directly with instructional staff about curriculum, professional development, and any targeted interventions underway. The physical move of secondary students to the new campus means the school's composition and instructional focus have shifted. A parent considering this school would benefit from asking what the building now prioritizes for its K-6 mission and what support structures have been redesigned to match that narrower grade band.

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.
