Best Public Schools in Zip Code 76635

Zip code 76635, serving the rural community of Coolidge, Texas, is home to two small public schools within the Coolidge Independent School District (Isd), which together educate just 287 students from Pre-Kindergarten through 12th grade.

Coolidge Elementary (PK-5, 147 students) stands out as the stronger academic performer, particularly in early mathematics. In the 2025-2026 school year, its 3rd graders achieved an exceptional 86.36% proficiency rate in math, nearly double the state average. However, this success is not sustained, as proficiency drops to 42.86% in 4th grade and 33.33% in 5th grade. The school has a history of strong rankings, peaking at a 4-star rating (73rd percentile) in 2023-2024. In contrast, Coolidge High School (6-12, 140 students) presents a mixed profile. While it boasts a perfect 100% graduation rate and 0% dropout rate, its academic performance is inconsistent, currently holding a 2-star rating (44th percentile). The high school excels in English/Language Arts, beating state averages in 7th, 8th, and English I Reading, but struggles significantly in 6th grade math (10.34% proficient vs. 38.57% state) and 8th grade Social Studies (11.11% vs. 31.69% state).

Both schools serve a high-poverty population, with over 72% of students qualifying for free or reduced lunch. The district invests heavily in its students, spending $11,783 per student at the elementary and $13,386 at the high school, well above national averages, and maintaining very low student-to-teacher ratios of about 9.7:1. Despite these resources, academic results are inconsistent, suggesting a need to translate investment into more uniform achievement. The high school's perfect graduation rate alongside below-average test scores creates a paradox, indicating a focus on student retention and completion that does not always align with grade-level academic mastery. The most notable finding is the dramatic drop in math proficiency between 3rd and 4th grade at the elementary school, pointing to a potential "middle school slide" as students transition to the high school in 6th grade.
