The Storm King School looks stable. The school holds only 8 months of operating cushion, unusually thin for a boarding school's residential capex load. Revenue runs 89% tuition-dependent (peer median 83%), heavier than the boarding cohort typically carries, so the cushion does real work. Staff compensation runs 48% of expenses, leaner than the peer median. NACUBO Composite Financial Index: 3.7 / 10, adequate — monitor.
The Storm King School reported $12.9M in revenue against $12.4M in expenses in fiscal year 2023, the most recent filing on record. Net assets stood at $8.4M — about 0.68x annual operating expense.

Why “revenue scale” and not “endowment per student”: independent-school 990s don’t carry per-school enrollment, and NCES PSS coverage is partial, so we cannot divide endowment by a verified student count for every school. The bar above is each school’s latest reported total revenue. True endowment-per-student is scheduled for v1.1+ once Schedule D Part V parsing lands.
Peers are scored by similarity along three equal-weighted dimensions: size cohort (Form 990 employee count + max-revenue tier, a proxy for student enrollment, which the 990 does not carry), geographic region (eight-region grouping), and association overlap (NAIS, NBOA, regional councils). We rank the top 20 nearest peers and chart the first 12 by latest reported revenue. Values are the school’s most recently filed total revenue on IRS Form 990.
