Summary:
The Sundown Independent School District (Isd) is home to a single high school, Sundown High School, a small rural institution serving grades 9 through 12 with a total enrollment of 184 students. This school stands out for its exceptionally low student-to-teacher ratio of 7.8:1 and high per-student spending of $18,524, which is well above the Texas average, creating an environment ripe for individualized attention.
Academically, Sundown High School shows a mixed but notable performance. It is a clear standout in Algebra I and English II Reading, scoring 72% and 73.17% proficient respectively in the 2025-2026 school year, significantly outpacing the state averages of 54% and 59.88%. However, the school has experienced a sharp decline in Biology, dropping from 87.5% proficiency the previous year to 68.85%, now below the state average of 70.51%. Similarly, U.S. History scores at 67.44% also trail the state average of 70.17%. The school’s graduation rate is exceptional at 97.2%, with a remarkable 0.0% dropout rate, indicating strong student retention and support systems despite a 45.65% economically disadvantaged population.
An interesting finding is the disconnect between the district’s elite ranking and the school’s more modest standing. The district is ranked 62nd out of 951 in Texas (93rd percentile, 5 stars), while the high school itself is ranked 694th out of 2009 (65th percentile, 3 stars). This suggests that the district’s high performance is likely driven by its elementary and middle schools. For parents, Sundown High School offers a small, well-funded environment with strong math and English outcomes and an outstanding graduation record, though recent dips in science and history warrant attention.
