Examinations 1974 to 1995
Results from pupils aged 15 and 17 have always been a performance indicator for schools. The GCE (General certificate of education) was introduced in 1951, this comprised of two parts, the O-level (normally taken when the pupil is 15 at the start of the year) and the A level (normally taken when the pupil is 17 at the start of the year). In 1965 for pupils leaving school the CSE was introduced as well, this provided an alternative qualification for those not taking the O-level. Both were replaced by the GCSE in 1988 which remains today. For pupils aged 17, the AS level was introduced in 1989 which provided the same difficulty as A levels but with half the content.
