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 2019 to 2020, from $25M to $33M (+36%).
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 21% · 2018 25% · 2019 29% · 2020 26% · 2021 19% · 2022 20% · 2023 25% · 2024 24% · 2025 23%. Grants only. Government contracts and fees sit inside program revenue.
26% of MASTERY CHARTER HIGH SCHOOL’s revenue is contributions — more donation-reliant than the typical peer (23% for the typical peer).
