Continued teaching kids computer programming, refined curriculum, held a special event (robot competition). We take students through 8 levels of mastery from beginner all the way to being a job-ready, certified programmer. Our curriculum ends with preparation for the oracle professional certification exam, which permits direct entry into the workplace upon high school graduation without requiring a college degree. Young students' lives are positively impacted through the critical thinking skills and self-confidence they gain from learning with organization.

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 $422k to $200k (−52%).
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 24% · 2022 38% · 2023 18% · 2024 31% · 2025 16%. Grants only. Government contracts and fees sit inside program revenue.
32% of WINTRISS TECHNICAL SCHOOLS INC’s revenue is contributions — about as donation-reliant as the typical peer (79% for the typical peer).

Who funds it, year by year
2018 → 2023: the base broadened from 1 funder to 2 funders, grant income fell $61k → $20k.
3 of 5 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 61% 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 WINTRISS TECHNICAL SCHOOLS INC’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
WINTRISS TECHNICAL SCHOOLS INC leans on a few funders — its largest provides 55% of grant income and the top three 98%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
61% 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 WINTRISS TECHNICAL SCHOOLS INC.
Largest funder’s share by year: 2018 100% · 2020 100% · 2021 72% · 2022 71% · 2023 50% — 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
61% of WINTRISS TECHNICAL SCHOOLS INC'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 $383k that is directly attributable, 99% of it comes from funders outside California, across 2 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $604k 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.
