[Welsh verb ‘to extend’]
The office of Her Majesty's Inspectorate for Education and Training in Wales, funded by the National Assembly for Wales but independent from it. For Wales it is the equivalent body to Ofsted in England. Estyn is responsible for school inspections and for reporting on school achievement for all levels of compulsory education, as well as for pre‐schools, government‐funded training programmes, and colleges of further education, including adult education. Stated objectives are to deliver high‐quality inspection of individual education and training providers, and related services, and to provide advice, based on inspection evidence, to inform the Welsh Assembly in the formulation and evaluation of education and training policy.
