Christian Pritchard has been appointed as the new Head of Beechwood Park School in Hertfordshire from September 2023.
He is currently Head at Beachborough School in Westbury, Buckinghamshire.
Mark Hammond, Chair of the Board of Governors at Beechwood Park said: "The Board has been extremely impressed by Christian's vision and strong academic, pastoral and leadership skills.
"He is highly regarded as a Head, and is ideally placed to take Beechwood Park forward over the next few years, building on its reputation as a leading co-educational day and boarding prep school."
Christian Pritchard said: "I am thrilled and delighted to be joining Beechwood Park in September 2023.
"It is a remarkable school with a very bright future, where children learn with a tangible buzz of excitement.
"After visiting the school this term, and meeting the children, staff and governors, I feel that Beechwood Park is perfectly placed to provide a world class, sector leading, innovative learning experience to the children of Hertfordshire and beyond, which is tremendously exciting!
"I look forward to meeting and joining the Beechwood community, in due course, as we embark on this journey together."
Maureen Cussans, an experienced IAPS Head and Beechwood Park Governor, will lead the school in the role of Interim Head for the two remaining terms of this academic year.
She will work closely with Christian Pritchard to ensure a smooth transition next summer.
