Teach First was initially based solely in London, as part of the London Challenge initiative, until September 2006 when it expanded into Greater Manchester schools. The programme was subsequently extended to cover a total of 11 local areas: East Midlands, London, North East, North West, South Coast, South East, South West, East of England, West Midlands and Yorkshire and the Humber. In Wales Teach First was given a three-year contract by the Welsh Government to pilot a graduate training programme for three years from 2013 as Teach First Cymru. Teach First has not been established in Scotland, in 2013 the charity met with the General Teaching Council for Scotland (the independent body for teaching in Scotland) but was told the recruits would not be permitted to teach in Scottish schools, as the General Council will only allow those already holding teaching certificates to teach. The Educational Institute of Scotland opposed the expansion of Teach First into the country with "The Herald" describing Teach First as controversial. In 2017 Scottish universities offering teacher training unanimously agreed to not work with Teach First. In light of the Scottish Government putting out to tender a fast-track teacher training scheme. Since launching in 2002, Teach First has placed increasing numbers of participants in schools each year. Teach First expanded from recruiting for secondary school teaching into recruiting primary teachers in 2011. Teach First is increasingly seen as attractive to young professionals and career changers with 22% of applicants in 2014 coming from these backgrounds. Teach First launched a new campaign in October 2015 which focuses less on the social reward aspects of teaching and more on the challenge of a teaching career, following research by the Behavioural Insights Team. School Direct and School-Centred Initial Teacher Training are school based schemes where participants can earn a salary during training. The Teach First model has also been applied in other areas of public sector recruitment with Frontline for children's social work, Think Ahead for mental-health social work, Police Now a two-year graduate leadership programme of the Metropolitan Police, and Unlocked for prison officers. As of 2017, 26 ambassadors of the programme were in Head Teacher roles and 36 social enterprises had been founded by ambassadors. Seventeen of these are recognised as official 'Innovation Partners' including The Access Project, Boromi, The Brilliant Club, CPDBee, The Difference, Enabling Enterprise, First Story, Franklin Scholars, Frontline, Future Frontiers, The Grub Club, Hackney Pirates, Jamie's Farm, Maths with Parents, MeeTwo, Right to Succeed and Thinking Reading.
