The considerable impact on participating schools meant that it was an opportunity sample (schools and their history teachers had to be willing to accept researchers taking precious time over a period of several weeks). Essex was, however, in many respects, a typical, if large, local authority, and the project tried to ensure that the sample included students drawn from the full range of socio-economic status and ability, and that different types of schools, curriculum organization and teaching approaches were represented.
