Enrollment trend & projection

Total enrollment went from 587 in 2018 to 650 in 2022 — over 4 years.
+10.7%
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 Delbarton School's own published school profile (as of 2024-25): www.delbarton.org/admissions/school-profile ↗

If the recent trend holds…

At its recent rate of +2.6%/year, projecting from 2022's 650 students:

2025

2027
738

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 88 students projected to be gained by 2027 represent ≈ $1,408,000/year in tuition upside.

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