Enrollment trend & projection

Total enrollment went from 657 in 2018 to 575 in 2022 — over 4 years.
-12.5%
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 Gill St Bernard S School's own published school profile (as of 2024-25): www.gsbschool.org/admissions/school-profile ↗

If the recent trend holds…

At its recent rate of -3.3%/year, projecting from 2022's 575 students:

2023
556
2025
520
2027
487

≈ 88 fewer students by 2027 — a real revenue/relevance risk worth getting ahead of.

An extrapolation of the recent trajectory, not a forecast of the school's plans; ignores one-off shocks.

Revenue at risk

At tuition per student, the 88 students projected to be lost by 2027 represent ≈ $1,408,000/year in tuition at risk.

Tuition is an editable estimate (PSS doesn't publish tuition) — set it to your school's figure.
