The Youth Training Scheme (YTS) was the name in the United Kingdom of an on-the-job training course for school leavers aged 16 and 17 and was managed by the Manpower Services Commission. The scheme was first outlined in the 1980 white paper A New Training Initiative: A Programme for Action, and it was brought into operation in 1983 to replace the Youth Opportunities Programme by the government of Margaret Thatcher. Initially lasting one year or six months, the scheme was amended in 1986 to be so that it could be extended to two years.
