In comparison, Ft Sam Houston Elementary is a solid, above-average 4-star school (74th percentile) serving grades PK-5. It performs above state averages in most areas, though 4th-grade math (42.16% proficient) is a relative weakness.

Both schools benefit from significant resource investment, with per-pupil spending ranging from $14,697 to $18,443 and low student-teacher ratios of 11.2:1 at Cole and 12.6:1 at the elementary school. This creates a strong educational pipeline where students from the elementary school are well-prepared to enter the middle/high school, which then produces elite outcomes.
