What Riverhead Charter School does
Mission
To offer students a true choice in public education and promote the love of learning and the exploration of locality and environments.
As stated on its FY2025 Form 990.
Program
The school's main objective is to offer students a true choice in public education, which promotes love of learning and local exploration. The school's goal is to provide a rigorous community of learning, which is inviting and stimulating to students and parents, as well as staff. The school intends to reverse the current spiral of student failure and meet or exceed state and federal standards, to nurture the individual gifts of every student, and to prepare them for a rewarding community life. Revenue is generated from tuition fees from more than a dozen school districts for students who enroll at Riverhead Charter School.

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 $36M to $39M (+8%).
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 3% · 2018 4% · 2019 4% · 2020 1% · 2021 2% · 2022 3% · 2023 4% · 2024 2% · 2025 1%. Grants only. Government contracts and fees sit inside program revenue.
1% of RIVERHEAD CHARTER SCHOOL’s revenue is contributions — more earned-revenue than three-quarters of its peers (23% for the typical peer).

Where its funders are

Funder states come from each funder’s own filing. $211 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.
