The Common Entrance examinations are used for assessing boys and girls who transfer to senior schools at the ages of 11+ and 13+.
The syllabuses are devised and regularly monitored by the Independent Schools Examinations Board, composed of representatives from the Headmasters' and Headmistresses' Conference, the Girls' Schools Association and The Independent Association of Prep Schools.
The papers are set by examiners appointed by the Board, but the answers are marked by the senior school for which a candidate is entered.
