Lake Granbury Academy Charter School

The Lake Granbury Academy Charter School district consists of a single campus, Lake Granbury Academy, which serves grades 7 through 12 with a total enrollment of just 47 students, classifying it as a very small high school.

Lake Granbury Academy is facing a severe academic crisis, ranking in the bottom 1% of Texas high schools for the 2025-2026 school year (2006 out of 2009). This is a consistent downward trend, as the school has ranked in the bottom 5% for the past three years. Test scores are alarmingly low: only 16.67% of students scored proficient on the STAAR End-of-Course exams in Biology and U.S. History, compared to state averages above 70%. For the 2025-2026 school year, the school reported a 0% proficiency rate for 8th-grade students in Reading, Mathematics, and Social Studies. While the small sample size is a factor, this is a stark indicator of severe academic challenges. The school does report a 0% dropout rate, meaning it retains all students, but this contrasts sharply with the lack of academic proficiency.

The school spends $14,246 per student, a significant amount, yet the student-teacher ratio is a high 27.3:1, which contradicts the expectation of small classes and raises questions about how funds are allocated. A very high percentage of students (70.21%) are eligible for free or reduced lunch, indicating significant economic challenges. With only 47 students across six grade levels, the school faces challenges in offering a wide range of courses and specialized instruction, which may be a primary driver of the low test scores. The combination of high spending, a high student-teacher ratio, and critically low test scores points to a fundamental breakdown in instructional effectiveness that requires urgent intervention.
