Summary

Sinton High School in Sinton, TX, is a mid-sized school serving 547 students in grades 9-12 within the Sinton Independent School District (Isd), where about 62% of students are economically disadvantaged. The school’s standout strength is its exceptional graduation rate, averaging over 96% for the last five years and reaching 97.4% in the 2023-2024 school year—higher than nearby Gregory-Portland High School (92.9%) and Calallen High School (93.0%). This suggests a strong, supportive culture that helps students complete their coursework, even as academic test scores are more mixed.

Academically, Sinton shows a clear bright spot in U.S. History, where 71.07% of students are proficient, slightly above the state average. However, it struggles in other core subjects, underperforming the state in Biology (61.19% vs. 70.51%), English I Reading (52.98% vs. 55.43%), and English II Reading (53.62% vs. 59.88%). The school’s Algebra I performance has been volatile, jumping from just 24% proficiency in 2022-2023 to 54.74% in 2025-2026, which is now slightly above the state average. Compared to demographically similar Odem High School, Sinton lags in nearly every academic metric, such as Biology (61% vs. 80%) and English II (54% vs. 71%), indicating room for improvement. On the other hand, Sinton outperforms Taft High School significantly, with higher test scores and a much lower dropout rate.

An interesting pattern emerges in subgroup performance: Hispanic students at Sinton rank in the 56th percentile (3 stars), outperforming the school’s overall average, while White students rank in the 30th percentile (2 stars). The school also shows extreme inconsistency with English Language Learners and Special Education students, with rankings swinging from top-tier to bottom-tier in just one year. This volatility, combined with the gap between a high graduation rate and lower test scores, suggests that while Sinton excels at guiding students to graduation, it needs more consistent, data-driven academic support to ensure deeper mastery of the curriculum.
