The union organizes in all sectors from early years to further education and represents teachers in all roles including heads and deputies. The NASUWT claims to be independent of any political party, and seeks to influence educational policy on behalf of its members with national government and the devolved assemblies in Scotland, Wales and Northern Ireland.
The origins of the NASUWT can be traced back to the formation of the National Association of Men Teachers (NAMT) in 1919. The Association was formed as a group within the National Union of Teachers (NUT) to promote the interests of male teachers. The group existed alongside others within the NUT such as the National Federation of Class Teachers, the National Association of Head Teachers and the National Federation of Women Teachers (later to become the National Union of Women Teachers).
The formation of the NAMT was in response to an NUT referendum the same year, approving the principle of equal pay. This major change in salary policy had been achieved whilst many male teachers were away serving in the army during the First World War.
A subsequent three year campaign by the NAMT to further the interests of male teachers in the NUT saw its name changed in 1920 to the National Association of Schoolmasters (NAS) and finally resulted in secession of the NAS from the NUT in 1922. The secession came about indirectly following a decision at the NAS Conference that year to prohibit NAS members from continuing to also be members of the NUT after 31 December 1922.
The NAS aimed to recruit every schoolmaster into the NAS, to safeguard and promote the interests of male teachers, to ensure recognition of the social and economic responsibilities of male teachers, and to ensure the representation of schoolmasters on matters concerned with education with both the Local Education Authorities (LEAs) and Government. The NAS also maintained that all boys over the age of seven should be taught mainly by men and that schoolmasters should not serve under women heads.
As the secondary education sector expanded, the NAS built its organisation among male secondary teachers, it adopted the methods of collective bargaining and militant industrial action in pursuing a narrow range of pay and conditions issues related to the interests of full-time male 'career teachers'. The union secured a place on the Burnham Committee to negotiate teachers' salaries in 1961, following a series of strikes and rallies. In 1976, the NAS merged with the Union of Women Teachers (UWT) largely as a consequence of the Sex Discrimination Act 1975, which made it unlawful to exclude from membership on grounds of gender, and became the National Association of Schoolmasters/Union of Women Teachers (NAS/UWT). In recent years, the slash has been dropped from the name.
The NAS/UWT took part in long-running industrial action between 1984 and 1986, in support of a pay claim and the retention of the Burnham committee. Both the NAS/UWT and NUT lost members to the less militant Professional Association of Teachers and Assistant Masters and Mistresses Association.
NASUWT policy is determined by its annual conference, to which delegates are elected from over 300 local associations. Members also elect the National Executive Committee. This committee, together with the General Secretary and other elected officials, determine the day-to-day business of the union.
Relations with government
From 2003 to 2010 the NASUWT was involved in "social partnership" - a programme of meetings between union leaders, the Labour government and employers' organisations. The meetings were initially to discuss pay and workforce issues but developed into a forum for broader discussion on policy proposals. The National Union of Teachers chose not to participate in social partnership. The NASUWT argues that social partnership brought about benefits to teachers' terms and conditions through the "National Agreement – Raising Standards, Tackling Workload", especially the introduction of defined planning and assessment time for all teachers.
Social partnership was confined to the Labour government, and did not continue after the establishment of the Conservative and Liberal Democrat coalition in 2010. Instead, the union lodged a formal trade dispute with the government over workload, conditions of service, pensions, and jobs. In November 2011, members of the NASUWT voted to take strike action, and begin working to the letter of their contracts. The NASUWT set aside historic differences with the National Union of Teachers; a joint declaration in May 2012 led to a co-ordinated work-to-rule and strike action in autumn 2013. 
The NASUWT has initiated a number of influential campaigns in recent years, including a campaign leading to the abolition of a code of conduct proposed by the General Teaching Council, a campaign recognising the effects of cyberbullying, a campaign to preserve the anonymity of teachers from malicious or false allegations, a campaign to criminalise home education  and a campaign to bar members of the British National Party from the teaching profession.
The NASUWT headquarters is at Rednal in Birmingham, with the General Secretary's office in Covent Garden, London. The union has nine other offices in England, and a single office in each of Northern Ireland, Wales and Scotland.
