Summary:
Zip code 77478 in Sugar Land, Texas, is home to a single middle school, Dulles Middle, which serves grades 6 through 8 and is part of the Fort Bend Independent School District (ISD).
Dulles Middle is a large school with 1,254 students and a student-teacher ratio of 15.9:1. The school has earned a consistent 4-star rating from SchoolDigger for the past three years, placing it in the top 28% of Texas middle schools. A standout feature is its exceptional Algebra I program, where 98.56% of students taking the exam were proficient in 2024-2025—nearly double the district and state averages. The school also performs well in 8th-grade science, with 59.86% proficiency, outperforming both the district (55.54%) and state (46.25%). However, performance is uneven. While 6th and 8th-grade math and reading are strong, 7th-grade math is a significant weakness, with only 21.01% proficient in 2025-2026, well below the state average of 29.41%. Similarly, 8th-grade social studies is an area for improvement, with just 29.83% proficient, below the state average of 31.69% and the district average of 43.53%.
Despite over 55% of students being economically disadvantaged, Dulles Middle achieves above-state averages in most subjects, demonstrating effective support for its student body. The school's math performance is notably two-tiered: a struggling general 7th-grade population contrasts with a high-flying advanced Algebra I track. Year-over-year performance can be volatile, such as 8th-grade math swinging from 44.24% to 60.04% proficiency, and social studies dropping from 40.86% to 29.83%. Compared to the district, the school dramatically outperforms in Algebra I and 8th-grade math and science, but underperforms in 8th-grade social studies and 7th-grade math, indicating that while it has excellent instructional pockets, it is not uniformly superior across all subjects.
