The organization over time
Each line starts at 100 in 2022, so what you read is the shape rather than the size: 150 means half as much again as 2022, 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 2022 to 2023, from $1.6M to $2.6M (+62%).
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.
7% of NATIONAL SUMMER SCHOOL INITIATIVE’s revenue is contributions — more earned-revenue than three-quarters of its peers (82% for the typical peer).

Who funds it, year by year
2021 → 2023: the base narrowed from 2 funders to 1 funder, grant income rose $153k → $250k.
1 of 9 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 26% 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 NATIONAL SUMMER SCHOOL INITIATIVE’s funders (the co-funder graph). 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
NATIONAL SUMMER SCHOOL INITIATIVE has a broad base — no single funder exceeds 26% of grant income, and it takes 3 funders to reach half.
the vertical line marks half of all grant income — 3 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 NATIONAL SUMMER SCHOOL INITIATIVE.
Largest funder’s share by year: 2021 98% · 2022 36% · 2023 100% — broadly stable.
“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.
Where its funders are
NATIONAL SUMMER SCHOOL INITIATIVE draws 79% of its grant income from funders outside New York, across 6 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $960k arriving through sponsors registered in 1 state 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.
