Your state's public flagship
The University of Texas at Austin
The in-state tuition gap is the flagship's biggest draw — most in-state families pay far less than the out-of-state sticker. Average net price after aid runs about $19,857/yr. Admission odds depend on your student's GPA and test scores, not which high school they attend.

Pay for college in Texas
Texas's public scholarships
Texas families have two big levers: a guaranteed-admission rule for the top of each graduating class, and the need-based TEXAS Grant that pairs with it. Class rank does more here than almost anywhere.
Graduate in the top 10% of your Texas public-HS class and finish the required curriculum for automatic admission to TX public universities (UT Austin caps at the top 5%). (Must finish the required college-prep curriculum (Distinguished plan).)
Official program details ↗Texas's flagship need-based grant — no GPA gate to qualify (a 3.0 or top-third rank just gives priority when funds run short). (Enroll within 16 months of HS, ≥¾ time, in a bachelor's program.)
Official program details ↗Graduate at least a semester early with the Distinguished plan plus a 3.0 GPA and an 80th-percentile test (or top-10% rank) for a TEXAS Grant-sized scholarship. (Graduate at least a semester early with the Distinguished plan.)
Official program details ↗Eligibility rules change yearly — confirm with the official program before relying on it. Amounts are recent published figures; awards cover tuition/fees, not housing or books unless noted. Verified 2026-10-21.
Enrollment trend & projection
Private school enrollment comes from the NCES Private School Universe Survey (PSS), which is collected every other year — not annually like public-school data. The most recent published collection is 2021–22; NCES targeted spring 2026 for the 2023–24 release — we'll load it as soon as it's published.
