This is a study of the educational experience of Franco-Ontarians at the secondary level, dealing specifically with the development and achievement of French-language instructional units, and community expectations of such units. The report starts with a review of the history of secondary French-language education from 1848 to 1968, the year in which the public sector began to provide for the educational needs of French-speaking Ontarians. The second chapter examines the evolution of legislation applicable to French-language instructional units at the secondary level, and the implementation of the legislation throughout the province. The third section discusses the collection and statistical analysis of data collected from secondary school students, parents, and teachers from the Franco-Ontarian community. Analysis of these data indicates that the French secondary schools respond more adequately to the expressed needs of Franco-Ontarians than do the bilingual secondary schools. In addition to general reports and data gathered from the French-language advisory committees, the last chapter presents summaries and analyses of data collected in each region of the province. (AMH)
