$2,227,346 spent$2,586,573 earned by the program28% of program spendingPublications and standards - principles and standards for school mathematics (2000) outlines the essential components of a high-quality school mathematics program and calls for all students to engage in more challenging mathematics. Curriculum focal points (2006) identifies three important topics at each grade level from pre-k12 and is the next step in implementing the standards. Principles to actions: ensuring mathematical success for all (2015) describes the principles and actions that are essential for a high-quality mathematics education for all students. Nctm's three-book series, catalyzing change, identifies the vexing issues that have long plagued mathematics education in pre-k and elementary grades, middle school, and high school. High school mathematics reimagined, revitalized, and relevant (2024) provides a thoughtful and practical guide for educators, school district leaders, and policymakers to rethink and restructure high school mathematics by emphasizing the development of mathematical and statistical processes. Nctm also publishes three peer-reviewed journals covering all grade bands.

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 2021 to 2022, from $21M to $18M (−14%).
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 0% · 2019 0% · 2020 0% · 2021 0% · 2022 13% · 2023 9%. Grants only. Government contracts and fees sit inside program revenue.
3% of NATIONAL COUNCIL OF TEACHERS OF MATHEMATICS’s revenue is contributions — more earned-revenue than three-quarters of its peers (52% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 8 of the last 9 reported years ran a deficit.

Who funds it, year by year
2018 → 2023: the base broadened from 1 funder to 3 funders, grant income rose $16k → $676k.
2 of 5 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 9% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

How concentrated its funding is
NATIONAL COUNCIL OF TEACHERS OF MATHEMATICS leans on a few funders — its largest provides 83% of grant income and the top three 98%; half comes from just 1 funder.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $102k 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.
