Thousands of 'equivalent' level qualifications are to be dropped from school league tables, the Department for Education has announced.
Following proposals set out by Professor Alison Wolf last year, only 125 additional qualifications will be factored into the ratings, down from 3,175 at present.
It is hoped that this will put an end to a system that incentivises schools to encourage children onto poor-quality courses in order to boost their positions in the Performance Tables.
The stripped down list will be brought into effect from 2014, with full-course GCSEs, established iGCSEs, AS Levels and music exams at grade six and above all to remain on the list.
Education secretary Michael Gove said that the changes would ensure that children are receiving the right qualifications to acquire university places and good jobs.
"The weaknesses in our current system were laid bare by Professor Wolf's incisive and far-reaching review. The changes we are making will take time but will transform the lives of young people," he said.
"For too long the system has been devalued by attempts to pretend that all qualifications are intrinsically the same. Young people have taken courses that have led nowhere."
