What Oceti Sakowin Community Academy does
Mission
Through the work of the Academy, students in the Rapid City area will have an inclusive and diverse education that is driven by rigorous academics while grounded in the thought and philosophy of the Oceti Sakowin. The students will have a deep sense of belonging, higher engagement and motivation, which will lead to improved academic outcomes, holistic wellness, strong cultural identities and confidence knowing who they are and where they came from.
As stated on its FY2025 Form 990.
Program
The Academy is grounded in the thought and philosophy of people who walked this land first, the Oceti Sakowin. Culture and language of the Oceti Sakowin is seen, heard, and practiced throughout the Academy. Through the work of the Academy, all students will thrive in an educational system that is unlike any other in the area. During SY25, there were approximately 60 students. Our expectations is to add a class year as these students continue on in their schooling.

The organization over time
Each line starts at 100 in 2022, so what you read is the shape rather than the size: 150 means half as much again as 2022, 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 $88k to $759k (+759%).
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: 2025 14%. Grants only. Government contracts and fees sit inside program revenue.
100% of Oceti Sakowin Community Academy’s revenue is contributions — more reliant on donations than three-quarters of its peers (48% for the typical peer).

77% 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 Oceti Sakowin Community Academy.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $30k arriving through sponsors registered in 2 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.
