What Marburn Academy does
Mission
At Marburn Academy we celebrate students who learn differently, empowering them to awaken their potential, to achieve success in school and life, and to affect positive change in our communities.
As stated on its FY2025 Form 990.
Program
Marburn Academy is the only independent day school in central ohio devoted to serving the educational needs of students with learning differences such as dyslexia, executive function difficulties and attention issues. Marburn is accredited by the independent school association of the central states (isacs) and is one of only 15 schools in the nation to have its language instruction program accredited by the academy of orton-gillingham practitioners and educators (aogpe). Marburn Academy is a growing program that serves day students in grades 2-12 across three divisions, including a summer school program. Marburn also seeks to improve the quality of education available to people with learning differences throughout central ohio and the state. In this role, marburn acts as a resource for parents, a demonstration center for model programs, and a training center for educators, psychologists, and other professionals.

The organization over time
Each line starts at 100 in 2018, so what you read is the shape rather than the size: 150 means half as much again as 2018, 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 $15M to $16M (+6%).
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: 2021 10% · 2024 13%. Grants only. Government contracts and fees sit inside program revenue.
10% of MARBURN ACADEMY’s revenue is contributions — about as donation-reliant as the typical peer (48% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 4 of the last 8 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.

Who funds it, year by year
2017 → 2023: the base broadened from 8 funders to 18 funders, grant income rose $305k → $403k.
11 of 39 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 68% 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 MARBURN ACADEMY’s funders (the co-funder graph). Top 30 of 39 funders by total. 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
MARBURN ACADEMY leans on a few funders — its largest provides 43% of grant income and the top three 58%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
81% 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 MARBURN ACADEMY.
Largest funder’s share by year: 2017 42% · 2018 42% · 2019 36% · 2020 44% · 2021 56% · 2022 37% · 2023 45% — growing more concentrated.
“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.
How long its funders stay
52% of MARBURN ACADEMY's funders are still giving 3 years after their first grant; 67% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
68% of MARBURN ACADEMY'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 $1.0M that is directly attributable, 77% of it comes from Ohio funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $2.2M arriving through sponsors registered in 8 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.
