Summary

Theodore Bird High is a public high school located in Sonora, California, serving grades 9-12 with a total enrollment of 90 students. The school is part of the Sonora Union High School District, which is ranked 1054 out of 1543 districts in California and has a 2-star rating from SchoolDigger.

Theodore Bird High consistently underperforms compared to the district and the state of California in standardized test scores, with only 22.5% of students proficient or better in English Language Arts/Literacy and 7.32% in mathematics, compared to the district and state averages. The school also has lower graduation rates and higher dropout rates, as well as significantly higher chronic absenteeism rates. Additionally, Theodore Bird High serves a higher proportion of students from low-socioeconomic backgrounds, with 55.56% of students eligible for free or reduced-price lunch.

When compared to nearby schools, such as Sonora High and Bret Harte Union High, Theodore Bird High performs significantly worse across various metrics, including academic achievement, graduation rates, and chronic absenteeism. The school's declining performance over time, with its statewide ranking dropping from 1071 out of 1994 California high schools in 2014-2015 to 1762 out of 2162 in 2024-2025, is also concerning and suggests that the school may be facing significant challenges in improving student outcomes.
