Mainstreaming equality involves integrating equality considerations from the outset into how an organization operates, its policies and practices. Whether this works to the advantage of disabled people depends critically on the quality of understanding of equality issues for different groups. This paper begins by clarifying goals for social justice, social inclusion and equality and then considers the salience of disabled people as a social category. It briefly reviews different equality strategies, before focusing on mainstreaming and its potential to promote cultural change and socially just distribution. An analytical framework to support mainstreaming is outlined. The paper concludes by stressing the importance of disabled people's involvement with mainstreaming equality if outcomes are to promote social justice.
