What Rainbow School does
Mission
The mission of Rainbow Schools is to provide the highest quality experience to the childeren of hawaii without regard for income or ethnic background.
As stated on its FY2025 Form 990.
Program
Preschools/food service: five preschools served approximately 320 students and employed 80 faculty and staff. Our services are intended to meet the needs of young children between the ages of two and five years old. The state of hawaii department of human services licenses all of our locations. In addition, all of our sites are required to actively seek accreditation by the national association for the education of young children or the national early childhood program accreditation. Consistent with the schools' exempt purposes, meals are provided for these programs.

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 2021 to 2022, from $2.8M to $3.8M (+39%).
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: 2017 5% · 2018 5% · 2019 6% · 2020 4% · 2021 15% · 2022 31% · 2023 24% · 2024 24% · 2025 4%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 4 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
2020 → 2023: the base narrowed from 2 funders to 1 funder, grant income fell $60k → $349.
1 of 2 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 1% 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 RAINBOW SCHOOL’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
RAINBOW SCHOOL leans on a few funders — its largest provides 99% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
Largest funder’s share by year: 2020 100% · 2021 99% · 2022 97% · 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
100% of RAINBOW SCHOOL's grant income comes from Hawaii funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1k 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.
