LANSING -- Hours after a conference committee approved a measure prohibiting the Michigan Department of Education from spending funds on implementing national Common Core State Standards for mathematics and English, the full state House of Representatives approved the restriction as part of the overall budget on Tuesday.

House Democrats attacked the move following the budget's passage, with House Democratic Leader Rep. Tim Greimel (D-Auburn Hills) accusing Republicans of "catering to a radical agenda" by blocking funding for the standards, which are opposed by some groups as reducing local control.

The bill including the Common Core language is headed to the Senate for its consideration, with a vote possible as early as Wednesday.

The Michigan State Board of Education approved the standards in 2010 as one of 45 states which has implemented the guidelines at least in part. Following the state board's approval, local school districts have been implementing the standards in advance of the 2014-15 school year deadline, according to an MDE publication on the standards.

State Superintendent Mike Flanagan accused lawmakers of "playing politics" with education after the conference committee's vote Tuesday morning.

Additionally, an email purportedly sent to principals and superintendents by Martin Ackley, director of the MDE's office of public and government affairs, stated that without full implementation of the Common Core standards, the state's waiver from federal No Child Left Behind standards was at risk and all Michigan schools were in danger of failing to make acceptable yearly progress.

Ackley did not respond to a request to authenticate the email, which appeared to be sent from his state email address. Portions of the email were read and referenced on the House floor during discussions about the budget measure by Rep. Andy Schor (D-Lansing).

Rep. Tom McMillin (R-Rochester Hills) issued a statement Tuesday afternoon accusing MDE of using "the sky is falling rhetoric" regarding what he termed a "pause" in Common Core implementation.

"It is unfortunate that the Michigan Department of Education has used 'the sky is falling' false rhetoric applied to a pause in the budget on implementing Common Core. This pause will allow Michigan citizens to weigh in, for the first time, on whether we should hand over authority on standards taught in all our public schools to a private trade association (NGA) or not," McMillin said.

The Common Core State Standards were developed by the National Governors Association and the Council of Chief State School Officers and were completed in 2010 after receiving input from teachers, principals, administrators and other groups, according to the Common Core State Standards Initiative.

The Michigan Department of Education held a public comment period on the standards in March 2010 before voting to implement the guidelines in June 2010.

McMillin has introduced standalone legislation, House Bill 4276, to prohibit the implementation of both Common Core standards and tests derived from the standards. That bill is pending before the House Education Committee, of which McMillin is a member.

Ari Adler, a spokesman for House Speaker Jase Bolger, R-Marshall, struck a similar tone. Adler accused MDE officials of "ringing an alarm bell" over the provision. "It’s surprising that education officials are ringing an alarm bell over this when you consider that the Legislature has plenty of time to act before this funding change takes effect on Oct. 1 on a system that doesn’t impact schools until the spring of 2015," Adler said.

Gov. Rick Snyder has previously indicated his support for the Common Core standards, saying earlier this month that he felt the standards were "an important opportunity." Attempts to reach a spokesperson for his office for comment were unsuccessful Tuesday.
