Although systematic national surveys of the recruitment and personal profiles of school board members are regularly conducted in the United States, few demographic or ethnographic studies have been conducted in Canada, in general, or in Ontario, in particular. This paper reviews (1) the brief history of school board recruitment and constituency in Ontario; (2) the limited literature available in this area; and (3) the findings of two research studies that are part of the development of a longitudinal profile of Ontario school board trustees. A historical overview shows that in Ontario, as in the United States, upper and middle class domination of educational governance has, for a variety of reasons, existed since the pioneer period. Major conclusions drawn from the literature (Cistone 1974) and the two research studies (Jakes 1977 and 1982) are as follows: (1) although the majority of Ontario's employed citizens are found in the lower three socioeconomic groups, 75 percent of school board members come from the upper three classes of Canadian society; (2) four out of five Ontario school trustees are male; and (3) trustees' years of experience on the school board fall into quartiles, with a turnover rate of 25 percent of the incumbents at each election. Further study may be needed to determine the possible effects of a projected increase in trustees' terms of office from 2 to 3 years. (IW)
