A Department of Education technology chief abruptly quit Tuesday amid allegations that he misappropriated DOE funds, The Post has learned.

Peter Quinn, 69, managed the Division of Instructional and Information Technology, which oversees schools’ Internet access. His ouster comes after Ohio’s inspector general in December accused him of conspiring to rig $469,000 worth of price-inflated IT contracts with that state’s Workers Compensation bureau, when he worked there in 2015.

Upon learning of that report, the DOE suspended Quinn’s purchasing powers, and launched its own probe.

Quinn, whose salary was $180,000 a year, “resigned irrevocably by mutual agreement,” the DOE said.

Quinn could not be reached for comment. A DOE spokesman refused to give further details.

The Special Commissioner of Investigation for city schools, which is probing the NYC allegations, declined to comment.

Former schools Chancellor Carmen Fariña appointed Quinn to the tech post in November 2016.

At the time, Fariña announced that Quinn had served as chief information officer for Massachusetts “prior to joining the DOE.”

In fact, Quinn had unexpectedly resigned as Massachusetts CIO in December 2005.

Quinn e-mailed his Massachusetts staff that he was quitting because he’d become a “lightning rod” for opposition to IT initiatives he supported, the Boston Globe reported.

Quinn also came under fire for allegedly failing to properly report numerous trips to out-of-state conventions, but was cleared of wrongdoing.

Prior to joining the DOE, Quinn owned an Ohio company, Pquinnsolutions. He dissolved it eight months after the DOE hired him.

Quinn worked under DOE Chief Operating Officer Ursulina Ramirez.
