Summary:
Zip code 76673 is home to a single school, Mount Calm Independent School District (Isd), a small rural alternative school serving grades PK through 12 with a total enrollment of 168 students. As the only school in the area, it defines the educational landscape, offering a close-knit environment with a very low student-teacher ratio of 11.1 and a per-student spending of $13,148, which is relatively high for a small district. The school boasts a perfect 100% graduation rate and a 0% dropout rate, indicating strong student support and retention, though its academic performance on state tests is highly variable.
Mount Calm ISD shows notable strengths in specific subjects, particularly in Reading, where 4th graders achieved 80% proficiency in 2025-2026, significantly outpacing the state average of 53.04%. However, the school struggles consistently in Science and Social Studies, with 8th graders reaching only 6.25% proficiency in Social Studies in 2024-2025 compared to the state's 29.64%. The school's performance is also marked by extreme volatility due to its small class sizes; for example, Algebra I proficiency dropped from 72.73% in 2024-2025 to just 20% in 2025-2026, a 52.73 percentage point swing that likely reflects the impact of a single cohort of students.
With 58.93% of students qualifying for free or reduced lunch, the district serves a majority economically disadvantaged population. While the high spending per student and low class sizes suggest individualized attention, the mixed test scores—with many subjects below state averages—indicate that resources may be focused on student support and graduation rather than test preparation. For parents, this school offers a supportive, small-scale environment with strong graduation outcomes, but they should be aware of the inconsistent academic performance across grades and subjects, particularly in math and science.
