Summary:
The 76048 zip code in Granbury, Texas, is served by ten schools, including elementary, middle, and high schools, with the majority belonging to the Granbury Independent School District (Isd).
The standout performer in the area is Acton Middle, a 4-star school that significantly outperforms its district counterpart, Granbury Middle, which holds a 1-star rating. This creates a clear performance gap within the district. The largest school, Granbury High School, is a consistent 3-star performer with strong graduation rates. In contrast, Nettie Baccus Elementary is a struggling 2-star school, while the small charter Lake Granbury Academy is the lowest-ranked school in the zip code, despite having high per-student spending. Other alternative schools like Premier H S Of Granbury and Stars Accelerated High School serve specific student populations but do not match the overall performance of Granbury High School.
A key finding is the "Algebra I anomaly" at the middle school level, where both Acton Middle and Granbury Middle show very low proficiency in 8th-grade math but very high proficiency in Algebra I, suggesting top students are accelerated into advanced coursework. Furthermore, there is no clear link between spending and performance; the highest-spending school, Stars Accelerated High School, has a 1-star rating, while the top-performing Acton Middle has the lowest spending among traditional public schools. The Texasworks - Granbury school, with only six students and no test data, is a specialized program that cannot be compared to others.
