Enrollment trend & projection

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 -5.4%/year, projecting from 2022's 32 students:

2023

2025

A small or specialty program — naive trend math doesn't capture the school's full picture. Read the trend as directional, not predictive.

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