Summary:
The Harts Bluff Independent School District (Isd) is home to a single high school, Harts Bluff Early College High School, a small rural school in Mount Pleasant, Texas, serving 224 students in grades 9-12 with a very low student-teacher ratio of 9.7 to 1.
Harts Bluff Early College High School shows a clear split in academic performance. The school is a standout in science and English, significantly outperforming the state average in Biology (83.33% proficient vs. 70.51% state) and English I Reading (73.68% vs. 55.43% state) for the 2025-2026 school year. English I Reading also showed strong year-over-year improvement, jumping over 16 percentage points. However, the school struggles in foundational math and social studies, with Algebra I proficiency (50%) and U.S. History proficiency (63.64%) both falling below state averages. This creates a notable paradox for an "Early College" school, where small class sizes appear to benefit some subjects but not others.
Key metrics reveal a school with moderate economic disadvantage (59.82% free/reduced lunch) and a very low dropout rate of 0.4%. The school’s state ranking is volatile, ranging from the 73rd percentile in 2023-2024 to the 51st percentile the following year, before recovering to the 68th percentile in 2025-2026. This instability is driven more by the performance of other schools statewide than by dramatic changes in Harts Bluff's own test scores, which remain relatively stable. The most dramatic performance gap is between Biology and U.S. History, suggesting an imbalance in instructional focus that parents may want to investigate further.
