Mackelprang and Salsgiver establish the historical and societal context in which those with disabilities are marginalized, discuss the major groupings of disabilities, and finally offer a model for assessment and practice that human service practitioners can adopt. The book develops a contemporary perspective in which people with disabilities are considered valuable and contributing members of society. Using this book, students will find not only a prescription for professional assessment and practice, but also the necessary understanding of common issues those with disabilities face, the social contexts in which they live, and the tools to work with people with disabilities as equals and partners.
