A nationwide survey of Canadian school districts was undertaken to determine the extent to which 18 forms of acceleration were permitted and practiced. Of the high enrollment provinces, BC school districts' participation rates were highest in the most types of acceleration. A surprising number of districts did not allow some forms of acceleration. In most provinces and territories, options that emphasize engaging quick learners in advanced content were more often permitted than those that involved placing accelerants with older students, but the forms most often implemented included both content- and grade-based options. Quebec was the exception where school districts preferred grade-based options. (Contains 4 tables.)
