Gov. Andrew M. Cuomo Wednesday called for permanent extension of statewide “cap” limits that have held school-tax increases to record lows in recent years but did not reveal how much state-aid money would go to individual districts to help compensate for the loss in local tax revenues.

School taxes, which account for the bulk of property taxation, rose just 1.57 percent this year on Long Island — one of the lowest increases on record. The statewide caps, which have been in effect for three years, would expire in 2016 unless extended by state lawmakers.

The governor’s supporters, including many business leaders, have heralded caps as a signature accomplishment of his administration. School leaders have contended, on the other hand, that the tax limitations contributed to larger class sizes in many districts.

“The caps have been a resounding success,” said Robert Megna, the state’s outgoing budget director. “The governor thinks the property tax is a burden on New Yorkers.”

In a move that broke decades of precedent, the state Budget Division Wednesday did not release computerized rolls showing how much new state aid would go to individual districts under the governor’s budget proposal for 2015-16. Nor did budget officials say when, or if, such details would be provided.

Megna said ample time remained to work out those details before April 1. That’s the date when state lawmakers are required to adopt a final budget including a school-aid package.

Cuomo called for a statewide school-aid increase of $1.1 billion, or 4.8 percent, without revealing how the money would be distributed locally. The governor proposed aid increases be withheld from school districts if they failed to make student’s scores on standardized tests 50 percent of teacher evaluations.

The proposed increase is the largest advanced by Cuomo so far. It is substantially less, however, than the $2 billion-plus recently recommended by the state Board of Regents, which sets statewide educational policy.

Some Long Island school officials now cobbling together their local budgets speculated that Cuomo was holding back on details of his aid proposal in order to use the extra money as a bargaining chip.

“It’s holding our districts’ budget planning hostage for his reform effort,” said Roberta Gerold, superintendent of Middle Country schools and president of the Suffolk County School Superintendents Association. “It’s frustrating.”

Bill Johnson, superintendent of Rockville Centre schools, said he was disappointed by the latest tax-cap proposal, but encouraged somewhat by the proposed $1.1 billion aid increase.

“I was somewhat surprised to see that the governor came in with a rather generous offer to start,” said Johnson, a former president of the New York State Council of School Superintendents. “It’s a positive note. But of course, we have to know how the money will be distributed.”

Statewide reaction was mixed.

E.J. McMahon, president of the Albany-based Empire Center for Public Policy, a fiscally conservative think tank, called the governor’s proposed tax-cap extension “terrific news.”

Billy Easton, executive director of the Alliance for Quality Education, which includes major school groups, termed the governor’s aid and cap plans “really bad policy with good sound bites.”
