A major obstacle immigrants have in adapting to their new environment is ignorance of the host country's language. The Council of Europe has taken several measures to help migrant workers and their families adapt to the host country by giving them the opportunity to learn, or improve their knowledge of, its language. Model projects for teaching languages to migrant workers were organised in 1965-67: 2 in the countries of origin (Spain and Italy) and 5 in the host countries (Belgium, Netherlands, Germany, United Kingdom, and Switzerland). The Council then decided to extend these pilot experiments to other European countries, including Sweden. This report gives an account of action taken in Sweden on teaching the language to migrant workers. The report also includes: an outline of the opportunities available to adult immigrants wishing to learn Swedish; and a description of courses arranged with the Council's help. Initiatives taken during 1970 are quoted: the agreement between SAF (tr. Swedish Employers' Confederation) and LO (tr. General Confederation of Labour); the declaration by SIV (tr. National Immigration Board) concerning language classes for immigrants; and the official State survey on the situation regarding teaching immigrants. (NQ)
