This report looks at the provision of General Certificate of Secondary Education (GCSE) and International General Certificate of Secondary Education (IGCSE) subjects in England in 2013. Reports on GCSE provision have been produced by Cambridge Assessment every year since 2010. This is the first year that IGCSEs have been included in the data for the report. A decision was made to include IGCSEs due to the increasing numbers of candidates taking these qualifications as alternatives to GCSEs. In this report the level of provision is presented by different school classifications: school type, school attainment, school gender, school size and school deprivation level. However, it should be noted that the analysis is at the simplest level and takes no account of interactions between these classifications. The tables presented in this report cannot tell us the reasons why schools do not offer a particular subject. The data for these analyses were taken from the National Pupil Database (NPD). This is a database of results for all students in all subjects in schools and colleges in England. This report presents only the provision of GCSE subjects in schools with pupils taking GCSEs in 2013. Provision of applied and short course GCSEs was not investigated. Only accredited IGCSEs were counted in this report as non-accredited ones will no longer be included in the NPD extract from 2014.
