 Labelling Schools failing if they are unable to achieve at least 5 Cs, including English and Maths at GCSE, for 40% of their pupils has also been criticised, as it essentially requires 40% of each intake to achieve the grades only obtained by the top 20% at the time of the qualifications introduction.A number of reports have also suggested the licensing of competing commercial entities to award GCSEs may be contributing to the increasing pass rates, with schools that aggressively switch providers appearing to obtain an advantage in exam pass rates.In response to allegations of grade inflation, a number of schools have switched to other exams, such as the International GCSE, or the International Baccalaureate middle years programme.
