Widening participation--though it has only recently been labelled as such--has been a continuing concern for policy makers and higher education institutions in the United Kingdom since 1945 (and before). This article reviews the evidence for four key target groups--women, lower socio-economic groups, mature adults and ethnic minorities--to produce an overall assessment, a score card, of what has been achieved, and what remains to be done. It concludes that, while progress in the recruitment of women, mature adults and ethnic minorities has been substantial--though with some qualifications--it has been much less so for lower socio-economic groups.
