Canberra Girls Grammar School is looking for a new principal after Anne Coutts advised the board that she would be leaving the school later this year.
Her husband, Ian Coutts, has been elected Bishop of the Anglican Diocese of Bunbury, in Western Australia.
In a letter to parents, Board chair Belinda Moss said Ms Coutts had led the school successfully for the past seven and a half years.
“Her skills and considerable experience as a Principal have enabled her to introduce numerous innovations and build a high achieving, professional staff who are experts in educating girls,” she said.
“Anne is held in high regard by our School family and the broader community. She will be missed.”
The Board will undertake a national and international search to select and appoint a new principal.
A former medical researcher and science teacher, Ms Coutts was principal of three girls’ schools in the UK before coming to Australia to take up the Grammar position in 2011.
