What Santiago Middle School does
Mission
The mission of Santiago Middle School is to assist its students to attain an educational advantage by delivering a quality and disciplined public school education of unmatched value.
As stated on its FY2025 Form 990.
Program
Santiago operates its charter school under the belief that adolescents deserve a quality curriculum designed specifically for them and that middle school is a time for exploration and discovery for interests. While other middle schools state-wide are cutting their exploratory programs, santiago continues to work so that these invaluable classes remain a part of the curriculum. As a result, each student at santiago has the option of choosing two per year of the following electives: art, vocal music, drama, foreign language, industrial arts, home economics, band, orchestra, speech, reading, and musical theater. All of the elective teachers have received training in the areas of reading and writing, and they incorporate these lessons into their programs in support of santiago's standards-based curriculum.

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 $5.3M to $9.1M (+71%).
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 97% · 2018 98% · 2019 98% · 2020 98% · 2021 99% · 2022 98% · 2023 98% · 2024 96% · 2025 96%. Grants only. Government contracts and fees sit inside program revenue.
100% of SANTIAGO MIDDLE SCHOOL’s revenue is contributions — more reliant on donations than three-quarters of its peers (23% for the typical peer).
Surplus & reserves

Who funds it, year by year
2020 → 2023: the base broadened from 1 funder to 3 funders, grant income rose $21 → $1k.
1 of 6 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 1% 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 SANTIAGO MIDDLE SCHOOL’s funders (the co-funder graph). Top 5 of 6 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
SANTIAGO MIDDLE SCHOOL leans on a few funders — its largest provides 37% of grant income and the top three 98%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
38% 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 SANTIAGO MIDDLE SCHOOL.
Largest funder’s share by year: 2020 100% · 2021 100% · 2022 58% · 2023 78% — diversifying over time.
“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
63% of SANTIAGO MIDDLE SCHOOL's grant income comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $153 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.
