What Working Assumptions Foundation does
Programs
Art education - through a learner-centered educationprogram, wrkxfmly, we engage students from diversecommunities around the country to make photos that explorethe interplay of work and family in their lives. Ourteaching artists work with high school photography teachersto facilitate the wrkxfmly curriculum and to supportstudents' needs as they work through the assignment. Theyare trained not only to deliver and support engaged photoeducation but also in methods for working with students on,what can be for many, a sensitive topic. Art experience - we design and facilitate opportunities forreflection and conversation about the daily intersection ofwork and family life, through public art installations,online experiences, community events, and print materialsdesigned for schools, art venues, public and businessspaces. We offer exhibition installation as a "kit of parts" for a gallery featuring local and national photographic works.
$908,976 spentGrants program - as part of our high school photography program, wrkxfmly, which engages students to explore the theme of work and family in their lives, we offer a grant program to participating high schools so that they might further engage students and amplify the conversation around work and family through exhibitions, panels and presentations, the creation of print materials like posters, field trips to art shows exploring the theme, and more. We also offer grant opportunities that recognize and reward professional artists, writers, and scholars whose work rethinks assumptions of power and authority, addresses family diversity and changing roles, and explores ecologies of care.
$234,680 spentImprint - a publishing arm so that working assumptions can self-publish photography and project books of the work we do. There is no intention for any published books to be used as a revenue source - these books would be given away as promotional material or as resources for our education program.
$169,301 spentArt lab - working assumptions incubates, tests, and develops new ideas, projects, partnerships, and art that explore the work and family interplay, including caregiving and family-making. Working assumptions is especially interested in opportunities to further critical thinking about our values and our expectations about productivity, power, vulnerability, and nurturing. We systematically seek out and collaborate with similarly driven multimedia organizations and thought partners to further explore those values and expectations, and we do so by combining research, expertise, and the power of visual communication.

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 2019 to 2020, from $414k to $2.3M (+452%).
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 held at 1 funder, grant income rose $650k → $725k.
3 of 3 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 100% 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 WORKING ASSUMPTIONS FOUNDATION’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
WORKING ASSUMPTIONS FOUNDATION leans on a few funders — its largest provides 94% 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 WORKING ASSUMPTIONS FOUNDATION.
Largest funder’s share by year: 2017 100% · 2018 100% · 2019 100% · 2020 100% · 2021 100% · 2022 100% · 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
100% of WORKING ASSUMPTIONS FOUNDATION'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. Too little is directly attributable to place on a map.
Funder states come from each funder’s own filing. $12M arriving through sponsors registered in 3 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.
Against its field
WORKING ASSUMPTIONS FOUNDATION is better cushioned than half of the 5,127 arts & culture nonprofits its size.
