Summary:
The Chico Independent School District (Isd) is served by a single high school, Chico High School, a small rural institution with 166 students in grades 9-12 that has shown a strong upward trajectory in state rankings over the past three years.
Chico High School presents a story of two extremes in academic performance. The school is a standout in Biology and English, significantly outperforming state averages in 2025-2026 with 75% proficiency in Biology and 67% in English I Reading. However, it struggles profoundly in Algebra I, where only 14.29% of students are proficient compared to the state average of 54%, and in U.S. History, where proficiency is 51.52% versus the state's 70.17%. The school benefits from a very low student-teacher ratio of 8.8:1, which allows for personalized attention, and 50% of students are economically disadvantaged. The graduation rate is 88.2%, slightly below the state average, while the dropout rate is 1.8%.
The most encouraging trend is the school's consistent improvement in state ranking, moving from the 28th percentile (1-star) in 2023-2024 to the 51st percentile (3-star) in 2025-2026. This positive trajectory is highlighted by a remarkable 12.67 percentage point jump in English I Reading proficiency in just one year. The key takeaway for parents is that Chico High School is clearly on an upward path, with strong science and English programs, but has urgent, identifiable weaknesses in math and history that need targeted improvement to fully capitalize on its momentum.
