What Oak Meadow Montessori School Inc does
Mission
Oak meadow montessori school is rooted in the child-centered montessori philosophy, which fosters academic excellence, personal growth, and cultural awareness while nurturing children's spirits. A diverse community of life-long learners, we cultivate confident, independent, and compassionate human beings by providing the tools and experiences needed to embark on rich, meaningful journeys as responsible citizens of the world.the montessori approach provides the best possible foundation for teaching and learning. Because we believe it is our job to meet each student's individual needs, we also incorporate the best and most current available educational research and thinking into our teaching. We teach our students to experiment, test, analyze, observe, and practice in their own educations; we, too, approach our school as a laboratory for ongoing learning.

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 2020 to 2021, from $6.3M to $7.4M (+18%).
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 12% · 2022 13%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 7 of the last 9 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base broadened from 2 funders to 5 funders, grant income rose $29k → $65k.
5 of 8 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 84% 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 OAK MEADOW MONTESSORI SCHOOL INC’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
OAK MEADOW MONTESSORI SCHOOL INC leans on a few funders — its largest provides 56% of grant income and the top three 80%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
84% 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 OAK MEADOW MONTESSORI SCHOOL INC.
Largest funder’s share by year: 2017 51% · 2018 100% · 2019 100% · 2020 61% · 2021 56% · 2022 54% · 2023 56% — 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
60% of OAK MEADOW MONTESSORI SCHOOL INC's funders are still giving 3 years after their first grant; 88% 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
84% of OAK MEADOW MONTESSORI SCHOOL INC'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 $47k that is directly attributable, 89% of it comes from Massachusetts funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $248k 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.
