We select the schools using a broad range of criteria relating to size, location, language of instruction, urban and rural and so on. This ensures that the sample of schools is broadly representative of all schools in Wales each year. Estyn does not use any specific risk factors when deciding which schools to inspect each year, for example the appointment of a new headteacher. However, the Chief Inspector retains a statutory right to be able to trigger the inspection of any school at any time, for example, when there are very significant concerns about the standard of education provided by the school. The Chief Inspector also retains the statutory right to inspect without giving any notice to the school/provider.
