Educational advantage.

This issue of JERHRE examines topics relevant to a variety of issues connected with community-engaged research and the relationship of communities with research ethics committees (RECs). It also examines some of the ways in which risk is assessed by subject populations and by RECs. Educational activities are presented that will enable readers to more comprehensively assess the way RECs and communities can work together more easily and effectively, and that will enable RECs to better understand their own functioning, and that of subject populations as these respective groups assess risk. The following assignments are best conducted in small groups.
