The organization over time
Each line starts at 100 in 2018, so what you read is the shape rather than the size: 150 means half as much again as 2018, 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 2023 to 2024, from $11M to $16M (+50%).
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: 2019 0% · 2021 9% · 2022 1% · 2023 0% · 2024 0% · 2025 0%. Grants only. Government contracts and fees sit inside program revenue.
2% of INTERNATIONAL SCHOOL OF BROOKLYN’s revenue is contributions — more earned-revenue than three-quarters of its peers (23% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 0 of the last 8 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
2017 → 2023: the base broadened from 5 funders to 7 funders, grant income rose $22k → $97k.

How concentrated its funding is
INTERNATIONAL SCHOOL OF BROOKLYN leans on a few funders — its largest provides 34% of grant income and the top three 58%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
55% 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 INTERNATIONAL SCHOOL OF BROOKLYN.
Largest funder’s share by year: 2017 33% · 2018 42% · 2019 48% · 2020 66% · 2021 26% · 2022 22% · 2023 52% — 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
70% of INTERNATIONAL SCHOOL OF BROOKLYN's funders are still giving 3 years after their first grant; 74% 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
55% of INTERNATIONAL SCHOOL OF BROOKLYN'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 $261k that is directly attributable, 62% of it comes from New York funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $322k arriving through sponsors registered in 6 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.
