Summary:
The two public schools in zip code 76950, serving the Sonora, Texas area, are part of the Sonora Independent School District (Isd), which holds a 2-star rating and ranks in the 40th percentile statewide. Sonora Elementary serves grades PK-6 with 365 students, while Sonora Secondary School serves grades 7-12 with 278 students, creating a clear divide in performance and resource allocation between the two campuses.
Sonora Secondary School stands out as the district's stronger performer, particularly in high school grades. It boasts an exceptional 98.3% graduation rate and a 0.0% dropout rate, alongside competitive End-of-Course exam scores that often meet or exceed state averages in English II Reading and Biology. The school benefits from a very low student-teacher ratio of 8.5:1 and higher per-student spending of $16,440, suggesting significant investment in individualized support. In contrast, Sonora Elementary generally scores below state averages in Reading and Math for grades 3-6, though it showed a notable strength in 6th Grade Reading, where 70.37% of students were proficient in 2024-2025, well above the state average of 54.21%.
A key finding is the "middle school slump" at Sonora Secondary School, where 7th and 8th-grade performance drops sharply—only 12.82% of 7th graders were proficient in Math in 2025-2026, compared to the state average of 29.41%. However, the high school program appears to successfully re-engage students, as evidenced by strong graduation metrics. The district also shows inconsistent year-over-year scores, likely due to small class sizes, making trends difficult to establish. Overall, the district prioritizes secondary education with 34% higher spending and a 38% lower student-teacher ratio at the secondary level, a strategy that appears to pay off in high school success despite elementary and middle school challenges.
