Schools in Monte Alto ISD · Hidalgo County

The Rio Grande Valley's largest county stretches across the southern tip of Texas, and its public school landscape is as expansive as the region itself — 303 ranked schools spread across 21 districts serving cities like McAllen, Edinburg, Mission, and Pharr. That scale means real variation in performance, but the county's top end is genuinely impressive: Edinburg Collegiate High School and South Texas ISD Preparatory Academy both rank at the 99th percentile statewide, with Achieve Early College High School in McAllen close behind. Altogether, 57 schools place in the state's top quartile — a meaningful share worth examining for families prioritizing academic rigor.
