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 $22,383/yr. Admission odds depend on your student's GPA and test scores, not which high school they attend.

Enrollment trend & projection

Total enrollment went from 692 in 2018 to 709 in 2022 — over 4 years.
+2.5%
Why only 3 data points?

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.

For a more current snapshot, see Thayer Academy's own published school profile (as of 2024-25): www.thayer.org/admission/school-profile ↗

Revenue upside

At tuition per student, the 22 students projected to be gained by 2027 represent ≈ $352,000/year in tuition upside.
