About schools in Harris County

Houston anchors Harris County's sprawling public school landscape, which spans 68 districts and more than 1,000 ranked schools — one of the largest concentrations of public education anywhere in the country. Katy, Pasadena, and Humble add their own distinct district identities to the mix, but Houston itself is where the county's highest performers tend to cluster. Spring Branch Academic Institute and Cornerstone Academy both score at the 100th percentile statewide, pointing to genuine excellence within the city limits. With 204 schools in the top quartile statewide, families across this county have meaningful options worth investigating closely.
