Studies on the development of social policies have provided us with a rich body of knowledge. However, being based mostly on class, gender or racial analysis, this body of work has seldom used disability as an analytical framework. This article proposes a systematic research agenda for addressing this lacuna. Drawing on the political and institutional approaches, this article illustrates how mainstream theories on social policy development cannot be assumed applicable to disability policies ‘as is’. To apply them effectively, we argue, students of social policy need to rework them in light of the insights of disability studies. Such conceptual work would involve closer attention to the uniqueness of disability as a socio-political category. Integrating these social policy theories with disability studies will allow us to better identify the unique political and institutional factors behind the trajectories of disability related policy. We conclude this discussion with suggestions for future research.
