What Ronald C Wornick Jewish Day School does
Mission
Ronald c. Wornick jewish day school develops students who are socially and academically prepared to meet their full potential as engaged leaders committed to a life steeped in jewish ethics and values.
As stated on its FY2025 Form 990.
Program
A wornick k-8 education rigorously engages the mind, body and heart of each of our 219 students in our vibrant community of enthusiastic learners. Students are challenged to solve problems while considering ethical implications. They learn to work independently researching subjects using cutting edge technology and collaborating on academic and community service projects. We cheer our student athletes in physical education, intramural teams and spontaneous flag football games on our enclosed turf field. Our students learn to lead, to speak confidently in both hebrew and english, and to embrace diversity. They are committed to serving their community. Our thirty (30) plus years of wornick alumni include outstanding contributors to their high schools, colleges, professions, israel and jewish communities. Our graduates have robust jewish identities, a strong attachment to israel, and a deep foundation in critical thinking, ethical decision making and continuous learning.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2024 to 2025, from $11M to $20M (+79%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2021 8% · 2024 2%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 1 of the last 9 reported years ran a deficit.

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.
Who funds it, year by year

the vertical line marks half of all grant income — 1 funder to its left
85% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund RONALD C WORNICK JEWISH DAY SCHOOL.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $4.3M arriving through sponsors registered in 11 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
