There is a close relationship between education and citizenship. Liberal political theorists tend to spend much of their work justifying the role of educational institutions in political communities. However, the development of these proposals is usually thought for subjects who do not have disabilities, arbitrarily excluding a significant proportion of society. This not only happens at an educational level, it is replicated in various areas of social life. In this sense, in the present work I am going to propose that the adequacy approach proposed by Debra Satz is extremely valuable to think about the educational equity of people with disabilities. The choice is not accidental or arbitrary. Satz is a renowned philosopher whose interest in education and its importance in forming citizens for diverse and plural societies. To do this, I will begin by presenting three possible models of special education: the special school, integration and inclusion. Then the two paradigms that prevail in the characterization of disability will be addressed: the social model and the medical model. Instead, I will reconstruct the third proposal elaborated by Satz in order to evaluate with which inclusive education model and disability paradigm it is compatible and why it is presented as a valuable proposal in this field.
