The specialist schools' policy was originally proposed by the Conservative government. The idea of allowing schools to choose up to 10% of their student intake is also a contrast to the 'non-selective' principle of comprehensive schools highlighted by the Labour party. However, the New Labour Party has steadily promoted the specialist schools programme since their first administration in 1997 and 2001. Up to 2009, 88% of state schools were awarded specialist status. It has gradually been proved that the Specialist Programme is becoming one of the overhaul reforms in secondary education in England. This paper investigates the development and content of the specialist school policy, outlines relative plans, and analyses the controversy around the policy. According the analyses, following the Labour administration, specialist schools have become the main type of secondary education and considerable resources have been allocated the sector. In spite of the controversial issues and critics, the specialist school policy has gone beyond the traditional argument of the grammar/comprehensive debate and has transformed the entire sector of secondary education. It is therefore suggested that more research should be encouraged to investigate the various issues pertaining to specialist schools.
