Marylou McDermott, superintendent of Northport-East Northport Schools, has announced plans to retire on Jan. 9.
Though she had said in July that her last day would be July 21, 2015, McDermott said she needs to take care of her mother, who is ill.
She has about four years left on a contract that would have paid her $325,767 in annual compensation for 2014-15, with $244,708 in salary and the rest in benefits and other remuneration, according to the state Department of Education. McDermott's total compensation ranked 54th among 671 school superintendents in the education department database.
"I was fully prepared to spend the balance of the school year as the district's superintendent, but it is paramount that my energies be fully devoted to my family," McDermott, 61, said in a statement. "I refuse to do this job without being fully present."
The Board of Education approved a resolution at a meeting Monday night allowing McDermott to leave her post early and waiving the 12-month notification requirement in her contract.
"Dr. McDermott has had an extraordinarily positive impact on our school district," board president Julia Binger said in a statement. The district had a 96.7 percent graduation rate in 2012-13.
The board also passed a resolution approving Thomas Caramore as interim superintendent. Caramore worked for the district as interim assistant superintendent for human resources from 2012 to 2013.
McDermott has led the 5,693-student district since 2006. When she announced her retirement in July, she said it was to "pursue other professional opportunities."
She has been a teacher, assistant principal, principal and administrator in several Nassau County districts.
Officials said McDermott's early departure will not impact the search for her replacement.
Results from a community survey on the search will be held at 7 Wednesday night in the Northport High School cafeteria.
