The Queen’s School in Chester will say farewell to headmistress Sarah Clark next year as she leaves to take up the headship of a prestigious London girls’ school.

Mrs Clark will leave the city centre school in December 2017, after seven years in her post, to become the new headmistress of the North London Collegiate School from January 2018.

Chair of governors Marion Ardron said: “Mrs Clark has worked tirelessly for The Queen’s School and we congratulate her on her success.

“While retaining the school’s all-important academic heartbeat and pastoral excellence, she has developed opportunities for girls to grow in confidence and leadership and will be leaving Queen’s in a very strong position for this excellent work to continue.

“The governors will begin the recruitment process to identify her successor shortly and we anticipate that the reputation of the school will stand us in good stead in attracting the highest calibre candidates.”

North London Collegiate School is one of the most highly regarded independent girls’ schools in the UK, with the Good Schools Guide saying it is ‘academically second to none’ and ‘possibly the best advertising for girls-only education in the country’.

Inspectors ranked The Queen’s School top in every category of its latest inspection saying that pupils ‘make exceptional progress at all stages of the curriculum’ and that ‘self-confidence, a willingness to take risks, articulate and respect the views of others are evident in pupils of all ages’.

It is again in this year’s Sunday Times’ list of Top Ten Independent Schools in the North West and The Good School’s Guide says Queen’s is ‘for girls who aspire both academically and personally’.

Both schools are members of the Girls Schools’ Association.
