Examiners for GCSEs and A levels (GCEs) are employed by the awarding bodies, which award the qualifications and are regulated by Ofqual. Ofqual does not specify the qualifications required in order to become an examiner. The regulators' 'GCSE, GCE and AEA Code of Practice' (April 2009) sets out the responsibilities that awarding bodies must follow to ensure the standardisation of marking, including that “examiners should have relevant experience in the subject area”.
