Summary:
The Lake Granbury Academy Charter School district contains a single high school, Lake Granbury Academy, which serves grades 7 through 12 in Granbury, Texas, with a very small enrollment of just 47 students.
Lake Granbury Academy faces severe academic challenges, with test scores critically below state averages. In the 2025-2026 school year, the school reported 0% proficiency in 8th-grade Reading, Mathematics, and Social Studies, and only 16.67% proficiency on Biology and U.S. History End-of-Course exams—dramatically lower than the state average of roughly 70%. The school's state ranking has consistently been in the bottom 1-4% of Texas high schools, dropping from the 4th percentile in 2022-2023 to the 0th percentile in 2025-2026, indicating a worsening trend. A high percentage of students (70.21%) are economically disadvantaged, and the student-teacher ratio is 27.3:1, which is high for a small school and suggests a very limited faculty.
Despite spending $14,246 per student—above the Texas state average—academic outcomes are among the lowest in the state, pointing to potential inefficiencies in resource allocation. The school reports a 0% dropout rate, which is positive, but this contrasts sharply with the 0% proficiency rates, suggesting the school retains students but fails to provide grade-level academic skills. With only 47 students across six grade levels, the school likely struggles with limited course offerings and specialized teachers, compounding its academic difficulties. This combination of high spending, low performance, and a worsening trajectory makes Lake Granbury Academy a school facing significant challenges that require fundamental changes in instructional strategy.
