Best Elementary Schools in Zip Code 78239

This analysis examines six elementary schools in the 78239 zip code of San Antonio, Texas, which serve grades PK-5 and are part of four different districts: North East Independent School District (Isd), Idea Public Schools, Compass Rose Public Schools, and Heritage Academy.

The standout school in this area is Royal Ridge Elementary, which consistently achieves the highest state ranking (23rd percentile) and the strongest test scores, particularly in 5th-grade Reading where it nearly matches the state average. It also has the lowest poverty rate and a favorable student-to-teacher ratio of 10.4:1. In contrast, Idea Walzem Academy has experienced a sharp decline, dropping from the 45th to the 3rd percentile over three years, and now posts the lowest scores across all subjects. Montgomery Elementary shows the most improvement, jumping to the 30th percentile with strong 4th-grade Reading and Math scores that exceed state averages. Heritage Academy Of Windcrest spends the most per student ($15,200) and has the best ratio (9.5:1), but its performance is inconsistent, while Windcrest Elementary and Compass Rose Journey fall in the middle range.

Overall, the three North East Independent School District (Isd) schools (Windcrest, Royal Ridge, Montgomery) consistently outperform the charter schools in the area, despite serving similar demographics. A key takeaway is that higher spending does not guarantee better results, as Heritage Academy spends the most but does not achieve the top scores. Mathematics is a universal weakness across all schools, with average proficiency (26.5%) significantly trailing Reading (36.5%) and state averages. The average free/reduced lunch rate is 83.24%, indicating high economic disadvantage, and the average state ranking is just the 16th percentile, highlighting the academic challenges in this zip code.
