Summary:
The Three Rivers Independent School District (Isd) is home to a single high school, Three Rivers Junior/Senior High School, which serves grades 7 through 12 in a small, rural community. With only 254 students and a very low student-to-teacher ratio of 7.2:1, the school offers an intimate learning environment and high per-pupil spending of $18,788. However, the school’s academic performance is a mixed bag, showing notable strengths in some subjects while struggling significantly in others, creating a complex picture for parents to consider.
The school consistently outperforms the state in Biology and U.S. History, with 82.61% and 78.79% of students proficient in the 2025-2026 school year, respectively. In contrast, it faces major challenges in 8th Grade Reading, where only 16.67% of students met proficiency—a staggering 42 percentage points below the state average. Similarly, 8th Grade Social Studies (13.33% proficient) and Algebra I (26.67% proficient) are areas of concern. The school’s state ranking has been volatile, fluctuating between the 49th and 58th percentiles over the last three years, and its graduation rate is a solid 92.6% with a low dropout rate of 1.3%.
A key takeaway is the disconnect between the school’s resources and its outcomes. Despite small class sizes and high spending, performance in core subjects like reading and math lags behind, particularly in 8th grade. The dramatic drop in reading proficiency from 7th grade (42.86%) to 8th grade (16.67%) suggests a potential issue with the curriculum or a specific cohort of students. While the school excels in science and history, parents should be aware that students may graduate with a diploma but without strong foundational skills in math and reading, which could impact college and career readiness.
