Mission
A collaborative montessori environment that develops self-motivated, independent learners by integrating academic excellence and a respectful social community that results in confidence and lifelong achievement.

Program
Riverbend school provides educational services to approximately 200 children annually from pre-school to grade eight.

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.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2019 to 2020, from $9.0M to $17M (+92%).
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% · 2023 10%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 0 of the last 8 reported years ran a deficit.

the vertical line marks half of all grant income — 2 funders to its left
96% 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 RIVERBEND CENTER FOR MONTESSORI EXCELLENCE INC.
Largest funder’s share by year: 2017 72% · 2018 64% · 2019 59% · 2020 53% · 2021 71% · 2022 41% · 2023 34% — diversifying over time.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration.

Where its funders are
96% of THE RIVERBEND CENTER FOR MONTESSORI EXCELLENCE 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 $31k that is directly attributable, 62% of it comes from Massachusetts funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $663k 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.
