Summary:
Zip code 76233, serving the Collinsville area, is home to a single high school, Collinsville High School, which serves grades 6 through 12 with a total enrollment of 298 students and is part of the Collinsville Independent School District (Isd).
Collinsville High School presents a mixed academic profile with notable strengths and weaknesses. The school excels in high school English Language Arts and Biology, consistently outperforming state averages—for instance, English II Reading proficiency reached 75.47% compared to the state's 59.88% in the 2025-2026 school year. However, it struggles significantly in middle school mathematics and social studies, with 8th Grade Mathematics proficiency dropping to just 7.41% in the 2024-2025 school year, far below the state average of 44.81%. The school's state ranking has shown strong improvement, rising from the 50th percentile (2 stars) in 2023-2024 to the 69th percentile (3 stars) in 2025-2026. Key metrics include a very low student-teacher ratio of 11.1:1, a high graduation rate of 96.8%, and a low dropout rate of 0.4%, with 43.62% of students economically disadvantaged.
An interesting finding is the stark contrast between middle school and high school performance, suggesting that the high school teaching staff may be particularly effective in English and Biology. The school's low student-teacher ratio does not guarantee across-the-board success, especially in middle school math and social studies, indicating that instructional methods or curriculum may need attention in those areas. Despite academic gaps, the school maintains a strong graduation rate, implying that students are supported to stay in school. The rapid improvement in state ranking over three years is a positive trend, though the school must work to ensure that its high graduation rate translates into college and career readiness for all students.
