Enrollment trend & projection

Total enrollment went from 1,189 in 2018 to 1,225 in 2022 — over 4 years.
+3.0%
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.

If the recent trend holds…

At its recent rate of +0.7%/year, projecting from 2022's 1,225 students:

2023
1,234
2025
1,253
2027
1,272

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

Revenue upside

At tuition per student, the 47 students projected to be gained by 2027 represent ≈ $752,000/year in tuition upside.

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