Summary:
The Caddo Mills Independent School District (Isd) is served by a single high school, Caddo Mills High School, which educates 833 students in grades 9-12 and has earned a 4-star rating from SchoolDigger.
Caddo Mills High School stands out for its exceptional performance in English and science, significantly exceeding state averages. In the 2025-2026 school year, students scored nearly 20 percentage points higher than the state average in English I Reading and over 10 points higher in English II Reading and Biology. The school also boasts a near-perfect graduation rate of 97.9% and a 0.0% dropout rate, demonstrating a strong commitment to student success. However, the school shows a notable weakness in Algebra I, where proficiency rates fall 5.62 percentage points below the state average, suggesting a key area for improvement. The school is on a clear upward trajectory, with its state ranking improving from the 70th percentile to the 75th percentile over the past few years, and proficiency rates increasing in nearly every subject.
With a favorable student-teacher ratio of 13.7:1 and spending per student of $11,232, the school appears to use its resources efficiently to achieve strong outcomes. The district's single high school structure means that for most subjects, the school's test scores are identical to the district's, though an anomaly in Algebra I data likely reflects middle school students taking the exam early. Overall, Caddo Mills High School offers a high-quality education with standout English and science programs, a supportive environment for graduation, and consistent year-over-year improvement.
