GCSEs replaced by 'English Bac' in key subjects

17 September 2012 Last updated at 22:47 BST

The GCSE exam in England is to be replaced for core subjects by a qualification called the English Baccalaureate Certificate - which will be awarded for the first time in 2017.

The shake-up of the exam system will mean a single end-of-course test rather than modular assessments, and one exam board responsible for each subject.
