"This volume (no. 1 in the series) contains a general introduction. The material for this section is based on the work of the National Council for Innovation in Education, who published a pamphlet in September 1973 entitled Curriculum for the Senior High School, Part I: General Section. This pamphlet was sent to all schools and interested bodies for their comments. The principal ideas contained in the pamphlet and the comments which came in were considered by the Interim Council for Upper Secondary Education and the Ministry of Church and Education in White Paper No. 44 (1974-75) concerning further education. They were presented in the National Assembly in Bill No. 395 (1974-75) and in the debate of 5 June 1975, which is reported in Parliamentary Proceedings No. 60 ff. This is the background to the present edition, which was prepared in December 1975 after consultation with the Interim Council for Upper Secondary Education. In certain respects the English edition was brought up to date in November 1976." -- (Foreword)
