These changes are the result of reforms to performance tables which have removed the perverse incentives for schools to teach qualifications that were easy to achieve and/or had an inflated value in performance measures.

 Figures for 2006/07 and 2007/08 are provisional, all other years are revised.
 From 2011/12 onwards, BTEC and OCR qualifications awarded as part of the Qualifications and Credit Framework (QCF) are included in their respective BTEC and OCR qualification categories.
 Figures for 2013/14 are based on the new 2013/14 methodology where Professor Alison Wolf’s recommendations and the first entry policy have been implemented. Only those BTEC qualifications mentioned in the document at the following link are included: https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/411159/Archived-KS4_performance_tables_-_inclusion_of_14-16_qualifications_in_2014.pdf.
