Assembly Speaker Sheldon Silver and Assembly Education Committee Chairwoman Cathy Nolan today called for a two-year delay – “at minimum” – in using Common Core test results for “high-stakes” decisions for teachers, principals and students.

Silver and Nolan said in a statement that “New Yorkers share the same goal – to improve our schools and help prepare our students to be successful and college and career ready upon graduation.”

But given the concerns raised over the controversial new curriculum, particularly in connection with the use of test data in teacher evaluations, the Democratic lawmakers said it would be both “prudent” and “wise” to put the brakes on.

At the same time, they said, the state Education Department should “continue to develop Common Core aligned curricula and assist local school districts in developing their own curricula” so teachers will successfully be able to instruct and assist students in reaching their maximum potential.

This is a victory of sorts for NYSUT, which has been pushing for a three-year moratorium, and also for the union’s embattled president, Dick Iannuzzi, who is facing a challenge to his leadership by a UFT-backed slate that includes his own No. 2, Andy Pallotta.

Up to this point, Silver has held off on making any definitive pronouncements on how to proceed on the hot-button topic of Common Core, even as many of his members and his political allies (ie: NYSUT) have been clamoring for a moratorium.

Silver made it clear that he believed the case had been made for a delay of implementing the Common Core standards, but also said he wanted to wait and see what a subcommittee set up by Board of Regents Chancellor Merryl Tisch to address this issue came up with.

The subcommittee has not yet reported back, but is expected to do so as early as next Monday.

Gov. Andrew Cuomo also waited for months while the Common Core controversy swirled before getting involved himself, finally weighing in during his budget address last month.

Cuomo said he supports the Common Core agenda, but believes the way it has been implemented by SED is “flawed.” He called for creation of a special advisory panel that would recommend “corrective action” to be acted upon by the Legislature before the end of this session.

Some lawmakers, including Senate Education Committee Chairman John Flanagan, criticized Cuomo’s plan, saying action on Common Core cannot wait any longer.

Last week, senators hammered state Education Commissioner John King over Common Core at a hearing during which they pledged to take action themselves if SED doesn’t do so ASAP.

Silver and Nolan also noted the “persistent questions” and security concerns about SED’s plans to share student data with a private, third-arty vendor charged with setting up a database of this information.

“SED should delay the use of inBloom or any third party vendor in developing a ‘data portal’ until all these questions have been answered and the concerns fully satisfied,” they said.

SED officials announced last month that they had delayed the upload of student data to the Atlanta-based inBloom until at least April, due to technical complications.
