With teacher entries into the work force declining and current low rates of teacher transfers and retirements and older age groups, the teaching force in the province of Manitoba is getting older. To study these trends, the age distribution of teachers was noted for the years 1970 and 1975. A discussion is presented in this report on trends in age distribution of Manitoba teachers, and also tables containing the following data: (1) age distributions for the years 1970 and 1975 in percentages; (2) numbers of teachers in each age category for those years; and (3) the pattern of change apparent in the age profiles. Projections are offered on the age composition of the teaching force in the province in the years 1980 and 1985. (JD)
