Summary:
Zip code 77055 in Houston, TX, is home to two middle schools within the Spring Branch Independent School District (Isd), serving grades 6-8, and they represent a dramatic contrast in academic performance and student demographics.
Cornerstone Academy is the standout school, ranked #6 in Texas out of 2,335 middle schools and earning a perfect 5-star rating for three consecutive years. Its test scores are near-perfect, with 98.47% proficiency in 6th-grade Reading and 97.99% in 8th-grade Math. In stark contrast, Landrum Middle ranks in the 28th percentile (1,687th in Texas) and has received a 1-star rating for three years, with average reading proficiency around 45.4% and math proficiency around 27.9%. A key paradox is that Landrum spends $2,322 more per student ($12,748 vs. $10,426) and has a better student-teacher ratio (12.6:1 vs. 15:1), yet achieves far lower results. However, Landrum has a notable bright spot: its Algebra I End-of-Course exam scores are excellent, with 86.27% of students proficient, far exceeding the state average of 54.03%.
The most defining difference between the two schools is the socioeconomic gap: Landrum has a 90.97% economically disadvantaged rate, while Cornerstone has only 15.13%. This disparity strongly correlates with the performance chasm, as Cornerstone’s student body has greater access to resources. Cornerstone’s success is driven by a rigorous curriculum and motivated student body, not smaller class sizes. For parents, this zip code offers a choice between a top-tier, elite academy and a struggling traditional school with a standout advanced math program, both within the same district.
