Enrollment trend & projection

Total enrollment went from 95 in 2018 to 118 in 2022 — over 4 years.
+24.2%
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 +5.6%/year, projecting from 2022's 118 students:

2023
125
2025
139
2027
155

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