Summary:
Zip code 78203 in San Antonio is home to two high schools serving grades 6-12 and 9-12, presenting a stark contrast in educational outcomes despite both serving predominantly low-income student populations.
St. Philip's College Early College High School is the standout school in this area, ranking in the 97th percentile statewide (55th out of 2,009 high schools) with a 5-star rating. This San Antonio Independent School District (Isd) school boasts exceptional academic performance, with proficiency rates in Algebra I (93.94%), Biology (94.29%), and English II (95.18%) that are dramatically higher than state averages. It also maintains a high graduation rate of 93.8% and an extremely low dropout rate of just 0.6%. In contrast, Idea Eastside College Preparatory, part of Idea Public Schools, ranks in the 16th percentile (1,686th out of 2,009) with a 1-star rating, and its academic performance consistently falls below state averages, with a lower graduation rate (85.4%) and a higher dropout rate (3.9%).
The data reveals that the early college model at St. Philip's appears to be a powerful driver of success, allowing students to earn college credit while in high school and producing test scores nearly double the state average. Interestingly, resource allocation does not explain the performance gap: Idea Eastside has a lower student-teacher ratio (13.2:1) and only slightly less per-student spending ($10,157 vs. $10,261) than St. Philip's, yet its results are dramatically worse. This suggests that the instructional model and school culture are far more critical than these specific metrics. A troubling data point at Idea Eastside includes a reported 0% proficiency rate in 8th Grade Science for the 2024-2025 school year, which warrants immediate investigation into potential systemic issues in science education at that school.
