What Rosalyn Yalow Charter School does
Mission
The Rosalyn Yalow Charter School will strive to eliminate the learning achievement gap for economically disadvantaged urban children-including special needs students and english language learners-by using engaging and demanding education; a team teaching model, linking an experienced teacher with a master social worker in grades k-2 and with a teaching fellow in later grades; rich extracurricular activities (fencing, arts, chess) to educate the whole child; and family support counseling-all in order to graduate our students at or above grade level in literacy and math.
As stated on its FY2025 Form 990.
Program
The school features 11 key design elements: qualified staff focused on at-risk students; a robust response-to-intervention team, consisting of special education and esl teachers overseen by a director of assessment; a quality curriculum, consisting of core knowledge language arts, singapore math, and inquiry-based science; high-quality collaborators, including the bronx arts ensemble for art, dance, and music, and a family support group with in-house personnel and chess and fencing coaches to organize competitive chess and fencing programs; meticulous data-driven instruction, guided by step literacy assessment and nwea map for math; and comprehensive professional development for teachers (40 days) including a one-month summer teacher workshop. We promote a team teaching model, pairing an experienced lead teacher with a teacher with a social worker background in grades k-2; and family involvement, beginning with home visits by teachers prior to the start of school. We are implementing a strong school culture built on character and using the disciplined activities of arts, chess, and fencing to develop the whole child; we have a low student-teacher ratio of 11:1, an extended school…

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 2022 to 2023, from $10M to $40M (+286%).
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: 2017 12% · 2018 8% · 2019 7% · 2020 5% · 2021 14% · 2022 17% · 2023 17% · 2024 4% · 2025 4%. Grants only. Government contracts and fees sit inside program revenue.
4% of ROSALYN YALOW CHARTER SCHOOL’s revenue is contributions — more earned-revenue than three-quarters of its peers (23% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 9 reported years ran a deficit.

Who funds it, year by year
Grant support over time, funder by funder — shade shows the grant size each year.
1 of 3 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 6% 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 ROSALYN YALOW CHARTER SCHOOL’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
ROSALYN YALOW CHARTER SCHOOL leans on a few funders — its largest provides 88% 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
94% 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 ROSALYN YALOW CHARTER SCHOOL.
“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
ROSALYN YALOW CHARTER SCHOOL draws 100% of its grant income from funders outside New York, across 2 states in all.
Funder states come from each funder’s own filing. $10k arriving through sponsors registered in 1 state 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.
