What Ross Valley Charter School does
Mission
Our mission at rvc is to encourage curiosity and inquiry, foster cultural competency and social-emotional learning, and develop a confident love of learning. Our program goes beyond progressive education by using inquiry, exploration, (continued on schedule o)......and hands-on, immersion-based experiences. The multi-age experience creates strong bonds and a solid foundation for exploration. At rvc, our active, learning-by-doing approach prepares students to work effectively together in teams, think critically, seek information to solve problems, and be lifelong learners and culturally competent members of our diverse global community.
As stated on its FY2025 Form 990.
Program
Ross valley charter (rvc) is a progressive tk-5 public charter school open to all california residents that develops lifelong learners by giving students the tools and support to follow their natural curiosity. Rvc's inspiration began more than two decades ago when a group of parents in the ross valley school district sought an alternative approach for their children's education. After much research, they chose to model their program, called the innovative learning community (ilc), on the reggio emilia approach, which is based on the belief that children learn by constructing their own knowledge within the context of relationships with peers, teachers, and parents, and that the teacher is a guide and facilitator who collaborates, co-learns, and researches with the students.

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 2022 to 2023, from $1.0M to $2.0M (+94%).
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: 2018 62% · 2019 73% · 2020 83% · 2021 93% · 2022 89% · 2023 87% · 2024 85% · 2025 87%. Grants only. Government contracts and fees sit inside program revenue.
95% of ROSS VALLEY CHARTER SCHOOL’s revenue is contributions — more donation-reliant than the typical peer (48% for the typical peer).

Who funds it, year by year
2018 → 2023: the base broadened from 3 funders to 7 funders, grant income fell $153k → $49k.
6 of 13 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 92% 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 ROSS VALLEY CHARTER SCHOOL’s funders (the co-funder graph). Top 12 of 13 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
ROSS VALLEY CHARTER SCHOOL leans on a few funders — its largest provides 51% of grant income and the top three 87%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
92% 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 ROSS VALLEY CHARTER SCHOOL.
Largest funder’s share by year: 2018 98% · 2019 99% · 2020 46% · 2021 56% · 2022 65% · 2023 33% — 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
67% of ROSS VALLEY CHARTER SCHOOL's funders are still giving 3 years after their first grant; 46% 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
92% of ROSS VALLEY CHARTER 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 $43k that is directly attributable, 84% of it comes from funders outside California, across 5 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $482k 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.
