What Metropolitan Montessori School does
Mission
The Metropolitan Montessori School is dedicated to providing an inclusive, enriching, nurturing and rigorous environment where each child is seen as capable and encouraged to grow to their fullest potential academically, emotionally and socially. The dynamic partnership of child, parent, and teacher creates a consistent montessori framework offering "an education for life."
As stated on its FY2023 Form 990.
Program
On its FY2022 return the organization reported a significant change in how it conducts a program.
The school ceased conducting its program service and merged with the calhoun school.
Its own explanation, from Schedule O of that return (Part III, line 3).
The school's programs include: (a) the stepping stones program, a beginning montessori program for children who are two years and eight months to three years old; (b) the primary program designed for children between the ages of three years old to six years old; (c) the lower elementary program designed for children between the ages of six and nine years old and; (d) the upper elementary program which includes grades four to five; (e) the middle school program which is the equivalent of grades six to eight. In addition, the school provides specialty classes in foreign languages, music, visual arts, and in physical education, library and computer skills.

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 2022 to 2023, from $27M to $0 (−100%).
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 10% · 2022 21%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 6 of the last 7 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 narrowed from 4 funders to 2 funders, grant income fell $43k → $14k.
7 of 13 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 25% 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 METROPOLITAN MONTESSORI 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
METROPOLITAN MONTESSORI SCHOOL leans on a few funders — its largest provides 51% of grant income and the top three 70%; 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: 2017 32% · 2018 43% · 2019 72% · 2020 22% · 2021 67% · 2022 47% · 2023 99% — 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
45% of METROPOLITAN MONTESSORI SCHOOL's funders are still giving 3 years after their first grant; 77% 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
89% of METROPOLITAN MONTESSORI SCHOOL's grant income comes from New York funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $183k arriving through sponsors registered in 7 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.
