Financials
[8]What this school has to spend, and what it spends it on. Spending is not a measure of quality. Schools serving more students with higher needs receive more money.
Charter schools manage their own budgets rather than receiving a school allocation from the DOE, so the staffing and supplies breakdown the DOE publishes for district schools is not published for this school.
