Chris Darby, Vice-Principal of Colaiste Colmcille in Ballyshannon will be the new President of St Eunan's College in Letterkenny.
He will replace former president, Fr Michael Carney, who steps down from the role at the end of this term on August 31 after spending 13 years in the job.
He will be the first lay person to take on the role in the St Eunan's College history. Fr Carney is expected to take up duties in an as yet undisclosed parish.
Meanwhile, another popular Colaiste Colmcille teacher is also on the move. Geraldine Diver, a native of Dublin, has been appointed vice principal of Killybegs Vocational School.
