The Chairman of Tralee's Institute of Technology Flan Garvey has announced his decision to retire from the position in July.
Mr Garvey informed the institute's governing body of his decision yesterday evening.
In a statement, the governing body said it accepted Mr Garvey's decision and acknowledged his significant contribution since 2001.
The institute said it has informed the Department of Education and Skills of Mr Garvey's decision and will be making no further comment on the matter.
Earlier this month Mr Garvey, a former Fianna Fáil councillor, was cleared of allegations that he plagiarised parts of a Masters he completed at the institute in 2008.
The national qualifications watchdog, Quality and Qualifications Ireland announced that it would review IT Tralee's postgraduate validation processes as a result of the controversy.
