A Queens principal accused of using fraudulent schemes to boost his school’s graduation rate can never again work with city students — but will get a $1.8 million desk job, The Post has learned. Khurshid Abdul-Mutakabbir, who was removed as principal of Maspeth High School last July, won’t return to any city school as a principal, according to a settlement of misconduct charges. But he can stay on the Department of Education payroll for another seven years. Under Abdul-Mutakabbir, Maspeth HS created fake classes, awarded credits to failing students, and fixed grades to push kids out the door, the Special Commissioner of Investigation for city schools found, confirming exposès by The Post. Instead of trying to terminate Abdul-Mutakabbir, as city investigators recommended, the DOE settled the charges on Jan. 25 by fining him $12,000 – and barring him from working as a principal. But under the sweetheart deal – which DOE officials kept hidden for months – the disgraced educator, now age 47, will sit in an office until he “irrevocably” retires on Nov. 30, 2029. He will pocket his current $187,043 annual salary, and get all union-negotiated pay raises for principals. He will also enjoy paid vacations and holidays, plus full health and retirement benefits, which will cost at least $78,558 a year in addition. The total cost will come to more than $1.8 million.
