Summary:
The Sinton Independent School District (Isd) contains one middle school, E Merle Smith Middle, which serves grades 6 through 8 with 425 students in Sinton, Texas. The school has a strong student-teacher ratio of 12.4 to 1 and a zero percent dropout rate, but its academic performance reveals a dramatic split between advanced and on-grade-level programs.
The most striking finding is the extreme contrast in math performance. The school’s Algebra I program is exceptional, with 92.11% of students proficient on the End-of-Course exam—far above the state average of 54.03%. However, general 7th-grade math is in crisis, with only 7.62% of students proficient compared to the state average of 29.41%. This suggests resources and high expectations are concentrated on a small group of advanced students, while the majority of on-grade-level learners, especially in 7th grade, are being left behind. Reading is a relative strength across all grades, but still lags the state by 5 to 11 percentage points. Social studies is another significant weakness, with only 17.42% of 8th graders proficient versus the state’s 31.69%.
The school’s state ranking has been volatile, dropping from the 48th percentile (2 stars) in 2023-2024 to the 22nd percentile (1 star) in 2024-2025, before recovering slightly to the 29th percentile (1 star) in 2025-2026. With 64% of students economically disadvantaged and spending of $10,902 per student, the school has reasonable resources that are not translating into broad-based success. Parents should note that while the advanced math program is world-class, the school urgently needs to address foundational math and social studies instruction to ensure all students are supported.
