Summary:
The Granbury Independent School District (Isd) serves approximately 8,617 students across nine schools—five elementary, two middle, and two high schools—in a mid-sized Texas district ranked in the 60th percentile statewide.
The district shows a clear performance divide, with standout schools like Oak Woods School (an 88th percentile, 4-star elementary) and Acton Elementary (4-star) leading the way, while Nettie Baccus Elementary (2-star) and Granbury Middle (1-star) struggle significantly. The "Acton" schools—Acton Elementary and Acton Middle—consistently outperform their counterparts, with Acton Middle earning a 4-star rating while Granbury Middle sits at just the 26th percentile. A notable anomaly is that both middle schools achieve high Algebra I End-of-Course scores (over 82%), even though their general 8th-grade math proficiency rates are much lower, especially at Granbury Middle (13.81%). Stars Accelerated High School, a small alternative school with only 44 students, spends the most per student ($18,831) but has the lowest graduation rate (82.1%) and highest dropout rate (7.1%), indicating its specialized model is not yielding strong results.
Poverty is a powerful predictor of performance: Oak Woods School has the lowest free/reduced lunch rate (37.13%) and the highest test scores, while Nettie Baccus Elementary has the highest poverty rate (76.97%) and ranks in the 32nd percentile. Mambrino School is a mystery, dropping from a 4-star to a 2-star school in just one year, warranting further investigation. Additionally, schools with significant Spanish-language STAAR testing, like John And Lynn Brawner Elementary, show a testing gap where Spanish test-takers perform far below state averages, highlighting a need for stronger bilingual support.
