A SCHOOL which celebrated its 600th anniversary last year has been given the highest possible rating in its latest inspection.

The Chorister School, in Durham, was rated excellent in all areas by the Independent Schools Inspectorate (ISI), following its visit in January.

The school, which was founded for boys who sang at Durham Cathedral, is open to children aged between three and 13.

The Very Reverend Andrew Tremlett, Dean of Durham and chairman of school’s governing body, said: “From start to finish the report rightly reflects the outstanding quality of the education provided at The Chorister School and the very highest standards of attainment achieved by our pupils.

“It is a remarkable reflection on the dedication and professionalism of all the staff, and on the exceptional leadership given by the Headmistress, Mrs Day.’

The school, which has 195 pupils, was judged excellent for both parts of the inspection, regulatory compliance and quality of education.

Inspectors said pupils were confident, highly motivated, had excellent levels of independence and had a strong sense of responsibility.

Since the last inspection, the curriculum has been broadened to include Mandarin, Greek and critical thinking.
