This paper, while broadly arguing in favour of the common school, nonetheless accepts the possibility of distinct specialist institutions in the later years of secondary schooling. It also argues for a careful distinction between a comprehensive school and a comprehensive classroom; further distinguishing between grouping by reference to alleged overall or all-round ability (‘streaming’) and grouping by reference to current preparedness for particular studies (‘setting’). It favours the latter and is critical of a policy of inclusion that tends towards the (...) placing of students with special needs in the regular classroom. It argues throughout that practice and policy must be based on educational rather than social grounds, should they be in conflict. (shrink)
