Hartford (AP) — The commissioner of Connecticut's Department of Education says he won't serve a second term should Gov. Dannel P. Malloy win re-election.

Stefan Pryor has overseen the Democratic governor's education reform initiative and has become a source of controversy.

According to a statement released Monday by Malloy's office, Pryor is "actively seeking new professional opportunities." He called it a "true honor" to serve Malloy, the State Board of Education and the people of Connecticut. He said a lot has been accomplished over the past nearly three years, acknowledging "the work has not always been easy."

Pryor came under fire from teachers and parents for the state's efforts to impose Common Core, new education standards and guidelines, among other changes.

Malloy's office said there is no set timeline for Pryor's departure.
