Graham Kinrade will retire from his role as Chief Officer of the DESC next year.
Mr Kinrade believes the timing is right for both himself and the organisation, particularly with a new political administration due to come into place shortly after the start of the next school year.
Mr Kinrade began his career as a teacher in 1987 and progressed to hold roles including head teacher and school improvement adviser, before working as a director within Government Technology Services.
In 2020, he returned to lead DESC and since then, he has been responsible for a workforce of more than 2,000 staff, focusing on resetting relationships, strengthening leadership, and supporting the delivery of education across 37 schools and University College Isle of Man.
Mr Kinrade said: “Leading the Department has been an absolute privilege, and I’ve been extremely fortunate to work with such a skilled, dedicated and professional team.
“This has been a difficult decision; however, I believe the time is right.”
Daphne Caine MHK, Minister for Education, Sport and Culture, added: “Graham has shown a strong commitment to public service and education, always leading with professionalism and integrity.
“He cares deeply about his work, and he has made a positive impact in all his roles.”
An open process to appoint a successor will begin in the New Year.
