What Corporation of St Timothy's School does
Mission
Founded in 1832, st. Timothy's school is a college preparatory boarding and day school, preparing girls to assume positions of leadership with moral focus and courage, intellectual honesty and acumen, and the confidence to act responsibly and ethically in all areas of their lives. St. Timothy's instills a passion for learning, and is committed to the formation of character, spiritual growth, social responsibility, and a respect for diversity. Such commitments are the hallmarks of our heritage. St. Timothy's curriculum is based upon the international baccalaureate program, which is one of the most rigorous and advanced curricula today for preparing students for the varied challenges they will confront throughout their lives. St. Timothy's offers a rich and highly individualized program with superb resources in athletics, arts, clubs, world affairs and community service, capitalizing on the talents and strengths of each individual student.

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. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2017 to 2018, from $41M to $47M (+13%).
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 6% · 2025 6%. Grants only. Government contracts and fees sit inside program revenue.
20% of CORPORATION OF ST TIMOTHY'S SCHOOL’s revenue is contributions — about as donation-reliant as the typical peer (23% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 5 of the last 9 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base broadened from 23 funders to 30 funders, grant income rose $707k → $960k.
22 of 64 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 54% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of CORPORATION OF ST TIMOTHY'S SCHOOL’s funders (the co-funder graph). Top 30 of 64 funders by total. Association, not causation. 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.
How concentrated its funding is
CORPORATION OF ST TIMOTHY'S SCHOOL has a broad base — no single funder exceeds 26% of grant income, and it takes 4 funders to reach half.
the vertical line marks half of all grant income — 4 funders to its left
56% 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 CORPORATION OF ST TIMOTHY'S SCHOOL.
Largest funder’s share by year: 2017 34% · 2018 45% · 2019 26% · 2020 16% · 2021 36% · 2022 16% · 2023 40% — growing more concentrated.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. 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.
How long its funders stay
56% of CORPORATION OF ST TIMOTHY'S SCHOOL's funders are still giving 3 years after their first grant; 69% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
54% of CORPORATION OF ST TIMOTHY'S SCHOOL's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $2.8M that is directly attributable, 97% of it comes from funders outside Maryland, across 17 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $3.3M arriving through sponsors registered in 15 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.
