Enrollment trend & projection
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.

At its recent rate of -54.8%/year, projecting from 2022's 15 students:

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