Summary
C B Thompson Middle in Quinlan, TX, serves 671 students in grades 6-8 within the Quinlan Independent School District (Isd), a rural district where over 73% of students are economically disadvantaged. The school has recently declined to a 1-star rating, placing it in the bottom 20% of Texas middle schools, with overall performance significantly below state averages across core subjects. Its most critical weakness is mathematics, where only 13.33% of 6th graders and 23.03% of 7th graders were proficient in the 2025-2026 school year—roughly half the state average and far behind high-performing neighbors like Lone Oak Middle (44.83% in 6th grade math) and Caddo Mills Middle (50.97% in 7th grade math).
Interestingly, the school excels in its Algebra I End-of-Course exam, with a 93.94% pass rate that surpasses the state average (54.03%) and even outperforms Caddo Mills Middle (90.22%). This "Algebra I paradox" suggests the school effectively accelerates its top math students, but the vast majority of the student body is left behind, with foundational math skills critically underdeveloped. Reading scores, while below state averages (e.g., 34.12% vs. 53.52% in 6th grade), are not as catastrophically low as math, indicating the core instructional challenge is specifically in mathematics.
Compared to nearby schools, C B Thompson Middle is one of the lowest-performing in the region, with a 21st percentile rank that places it well below Lone Oak Middle (4-star, 74th percentile) and Bobby Summers Middle (3-star, 50th percentile). It is more comparable to Greenville Middle (0-star, 9th percentile) and Herman Furlough Junior Middle (1-star, 17th percentile). The school's per-student spending ($8,857-$9,614) is in the middle of the pack for the region, suggesting its challenges are not simply a matter of funding but likely relate to instructional strategies and resource allocation. The school is on a downward trajectory, and improvement will likely require a deep, systemic overhaul of its core math instruction for grades 6-8.
