Part of the Eleventh Annual Report to the Ontario Ministry of Education, this report describes the grade and program location of students who entered kindergarten in Ottawa and Carleton, Ontario in 1974, known as the K-74 cohort. The first section of the report deals with the K-74 cohort; later sections deal with students who joined either early or late immersion at the expected level of the K-74 cohort. Some of the factors examined by the study are the following: (1) patterns of transfer into and out of the immersion programs and proportions reaching the expected grade level at various points; (2) comparisons of grade level of students who had left the early immersion program with students from the K-74 cohort in the English-language program; and (3) analysis of the progress of three late-immersion groups who had entered a high school with a program emphasizing French instruction. The report contains a number of diagrams that illustrate the varied pathways of several groups of students, and tables and graphs that present the longitudinal data on students in various programs for each year from 1974-1983.
