Carmel College’s principal Rob Peacock will retire this summer after 14 years at the helm.
Mr Peacock joined the college in 1987.
His replacement has been confirmed as Mike Hill.
Mr Peacock said: “It has been a real privilege to be part of Carmel College.
“The staff and students here are simply outstanding and have made my job a real pleasure.
“I know Mike and I am confident that under his leadership Carmel will continue to flourish. I wish him every success.”
Mr Peacock and Mr Hill will work closely together over the coming month to ensure a smooth transaction.
Mr Hill said: “I feel extremely privileged to lead such a nationally renowned college. Rob has set the bar very high.
“My task is to sustain and develop the outstanding work Carmel does. When I first visited the college, I was bowled over by the excellent learning environment and the friendliness of both the staff and students.
“I have many happy memories of success on the rugby fields of St Helens and I’m looking forward to working with staff, students and governors to ensure that Carmel continues to have a positive impact on the whole of the local community.”
