The first round of a study of what happens to students after they leave Peel County (Ontario) secondary schools includes data from students who were in grade 11 in 1977-78 and 1979-80. A 10 percent sample (approximately 750 students in each group) was drawn from school records. Of these, 1,072 people (75 percent) were interviewed by telephone. Major findings of the study are as follows: (1) most former students are in the labor force, most in entry-level jobs; (2) few students enter formal job training programs; (3) the university is the postsecondary institution most frequently attended; (4) respondents' current activities are frequently not what they expected when in grade 11, especially so for those in the labor force; and (5) vocational students are less likely than other students to be at school and more likely to have had vague plans when in grade 11. The report describes the methodology with text and tables used to analyze the responses. A short discussion paper follows the official report and suggests changes in a variety of school practices.
