Before the introduction of the CSE, the majority of schoolchildren at secondary modern schools did not take externally set end of school examinations, and so left school without any nationally recognised qualifications. Though the introduction of the CSE did not, of itself, resolve the issue as the majority still left at the end of the fourth year without sitting an external qualification. By the late 1960s and early 1970s, some counties had introduced their own examinable qualifications for those leaving at the end of the fourth year. For example, the county of Monmouthshire in Wales awarded the Monmouthshire Certificate in Education.
