State school officials are asking the city's Department of Education to explain how it failed to reach its own goal of reducing class sizes by using a new influx of state money.
State officials said 54% of city schools saw either class sizes or their student-teacher ratios increase in the last school years, despite a $106 million plan the department unveiled last year to reduce class sizes in high-need schools.
The plan was produced in response to demands from the state, which had targeted a new influx of funds toward specific policies, including class-size reduction.
The state is specifically asking city officials for details on 70 schools that received $100,000 or more in the funds — but still saw class sizes and student-teacher ratios increase.
The Department of Education responded with a statement calling its progress in reducing class size "substantial" and saying it will provide the requested information to the state.
