WELLESLEY HIGH SCHOOL PARENT TEACHER STUDENT ORGANIZATION

What Wellesley High School Parent Teacher Student Organization does

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. 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 2017 to 2018, from $105k to $121k (+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.

Surplus & reserves

Operating surplus or deficit each year, and months of liquidity in hand. 5 of the last 9 reported years ran a deficit.

Who funds it, year by year

2019 → 2023: the base held at 1 funder, grant income fell $5k → $325.

2 of 3 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 98% 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 WELLESLEY HIGH SCHOOL PARENT TEACHER STUDENT ORGANIZATION’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

WELLESLEY HIGH SCHOOL PARENT TEACHER STUDENT ORGANIZATION leans on a few funders — its largest provides 90% of grant income and the top three 100%; half comes from just 1 funder.

98% 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 WELLESLEY HIGH SCHOOL PARENT TEACHER STUDENT ORGANIZATION.

Largest funder’s share by year: 2019 100% · 2020 100% · 2021 97% · 2022 51% · 2023 100% — broadly stable.

“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.

Where its funders are

98% of WELLESLEY HIGH SCHOOL PARENT TEACHER STUDENT ORGANIZATION'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 $300 that is directly attributable, 100% of it comes from funders outside Massachusetts, across 1 state.

Funder states come from each funder’s own filing. $12k arriving through sponsors registered in 2 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.
