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.
For a more current snapshot, see Keystone School's own published school profile (as of 2024-25): www.keystoneschool.org/admissions/school-profile ↗

Revenue upside
At tuition per student, the 79 students projected to be gained by 2027 represent ≈ $1,264,000/year in tuition upside.
