What Sigma Delta Tau Society does
Mission
Sigma delta tau empowers each member to reach her fullest potential by enriching the experience of women with similar ideals, building lasting relationships, promoting civic responsibility, and fostering personal growth.
As stated on its FY2025 Form 990.
Programs
Chapter services: the society provides services to its collegiate chapters including regular staff visits, publications and resources, oversight and guidance.
Publications: the society publishes a semiannual magazine in the spring and fall which contains both educational and sorority specific information. This magazine is sent to all initiated undergraduate and alumnae members, currently numbering about 30,000.
Conventions and conferences: the society holds conferences which disseminate leadership and educational information and materials. The national convention is a biennial event and collegiate leadership development programming is held annually.

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 2021 to 2022, from $6.1M to $4.7M (−22%).
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: 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. 1 of the last 9 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.

SIGMA DELTA TAU SOCIETY leans on a few funders — its largest provides 76% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
100% 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 SIGMA DELTA TAU SOCIETY.
Largest funder’s share by year: 2017 100% · 2018 100% · 2019 100% · 2020 100% · 2022 58% · 2023 100% — broadly stable.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration.
