Fifty-nine of New Jersey’s wealthiest school districts would receive no direct state aid for their operations next year — in effect, a 100 percent cut — under the governor’s proposed budget, according to state figures released on Wednesday.

The state would seek to reduce direct aid to nearly 600 districts by an amount equivalent to as much as 5 percent of their individual operating budgets, for an overall reduction of $820 million from the year before. The education cuts were revealed in detail for the first time since being proposed on Tuesday by Gov. Christopher J. Christie as part of his $29.3 billion budget plan.

For wealthier districts like Ridgewood, Millburn and Glen Ridge, that would mean losing the direct state aid that they receive for their classrooms — a relatively small percentage of their operating budget — forcing them to rely almost exclusively on local property taxes.

“It is by no means a death blow, but it is a heavy burden,” said Elisabeth Ginsburg, the school board president in Glen Ridge, which received $1.2 million in state aid this year, most of which paid for mandated special-education services. “You have to think carefully about how you’re going to go forward.”
