Summary:
The four public schools in zip code 77474, all part of the Sealy Independent School District (Isd), serve approximately 3,109 students across one high school, one middle school, and two elementary schools in a community with a high level of economic need, where an average of 66.9% of students qualify for free or reduced lunch.
The standout school in the area is Sealy Elementary, which has earned a 4-star rating for three consecutive years and ranks in the 80th percentile among all Texas elementary schools. This is a stark contrast to Selman Elementary, the district's other elementary school, which ranks in the 16th percentile and holds a 1-star rating. This performance gap is notable because Selman Elementary has a higher percentage of economically disadvantaged students (74.23% vs. 66.28%) and slightly higher per-student spending, suggesting that factors like teaching quality or school leadership are driving the difference. At the middle school level, Sealy J H struggles significantly in standard math, with 7th-grade proficiency dropping to just 5.21%, yet it excels in advanced Algebra I, where 81.69% of 8th graders taking the End-of-Course exam score proficient—far above state averages.
Sealy High School presents a mixed picture, ranking in the 43rd percentile (2 stars) with a strong 93.9% graduation rate but a declining trend over the past three years. The school performs at or above state averages in Biology and English I Reading, but significantly underperforms in Algebra I (40.22% vs. 54.03% state) and English II Reading. This suggests that students entering high school with weak math skills, as seen in the middle school, are not catching up, and reading proficiency declines in later years. Overall, the district ranks in the bottom 40% of Texas districts, with the elementary schools showing the widest disparity in performance.
