The Republican-led Senate once again on Monday approved legislation that would create a tax credit for educational donations that’s been long sought by the Catholic Church.

The measure was approved 47-15.

But the real fight over the tax credit is in the Democratic-led Assembly, where some lawmakers have expressed unease over a bill that is staunchly opposed by the state’s teachers ion.

“For several years, the Education Tax Credit has been the top legislative priority of the Catholic Bishops of New York State,” said Richard E. Barnes, executive director of the Catholic Conference. “Last year, we came closer than ever to passage, when Gov. Cuomo put his full support behind the initiative, backed by a bipartisan majority in the Senate. The obstacle then, as now, is the powerful public school interest groups, including the state’s teacher unions.”

Cardinal Timothy Dolan has personally lobbied lawmakers on the issue and has leaned on Gov. Andrew Cuomo to push for the measure as well. Dolan last week was in Albany to provide the opening prayer for the legislative session in the Senate. The Catholic Conference said the visit was meant to be “pastoral.”

The bill would provide a tax credit for those who give donations to educational programs that benefit public schools, as well as scholarship programs that aid parochial schools. The measure approved Monday was among a package of opening salvos at the start of the session, which included curtailing the gap elimination adjustment cuts to education as well as putting term limits for legislative leaders into law.

“As Cardinal Dolan has said, the Education Tax Credit is a no brainer in that it helps all schools and all families. For Catholic schools in particular, it can be a game changer in alleviating the funding crisis that has seen hundreds of quality school options for children across the state close in the past two decades simply because families cannot afford the rising costs. We hope today’s action by the Senate is a harbinger of good things to come, and we thank Senate Majority Leader John Flanagan for making it a priority.”

Cuomo last year linked the tax credit to the passage of the DREAM Act, which provides tuition assistance to undocumented immigrants.

Ultimately, both proposals fell out of the budget negotiations in March.
