Another area where teacher training is important is in the development of more senior staff, who can become 'champions' for entrepreneurship within their schools. In the UK, HTI, a not-for-profit organisation working in the field of leadership development at the interface between education and business operates a range of programmes to engage business leaders in an ongoing partnership with the education sector.. Activities include the "Stretch" programme that supports secondments of senior teachers into businesses (for periods ranging from four weeks to six months or longer), and the "Take5" initiative which helps businesses to develop their staff through challenging assignments in the education sector.
