What The Walden School of California does
Mission
Walden school (the "school"), was founded as a non-profit independent co-educational elementary school in pasadena, california. The school nurtures a child's natural wonder and personal dignity. A personalized, developmentally appropriate program is provided that encourages responsibility, initiative, child-led inquiry, ethical behavior and excellence. The school promotes positive conflict- resolution skills, understanding, and creativity in problem solving. Academic skills and concepts are taught through experience and socratic discussion, as well as through direct instruction and practice. The school teaches children to value and respect diversity. The school strives, therefore, to lay the foundation for wisdom, to encourage the spirit of renaissance learning, and to teach that we have stewardship for the world in which we live.
As stated on its FY2025 Form 990.

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 2018 to 2019, from $8.7M to $7.4M (−15%).
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 11% · 2022 9%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 9 reported years ran a deficit.

Who funds it, year by year
2020 → 2023: the base broadened from 2 funders to 10 funders, grant income rose $8k → $67k.
7 of 14 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 61% 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 THE WALDEN SCHOOL OF CALIFORNIA’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
THE WALDEN SCHOOL OF CALIFORNIA 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
61% 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 THE WALDEN SCHOOL OF CALIFORNIA.
Largest funder’s share by year: 2020 97% · 2021 79% · 2022 75% · 2023 21% — diversifying over time.
“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
50% of THE WALDEN SCHOOL OF CALIFORNIA's funders are still giving 2 years after their first grant; 57% 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
61% of THE WALDEN SCHOOL OF CALIFORNIA'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 $89k that is directly attributable, 62% of it comes from funders outside California, across 4 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $143k arriving through sponsors registered in 5 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.
