The present work is a master thesis at the Karl-Franzens University. The work is focused on the possibilities and limits of self-determination for people with severe disabilities. Following the theoretical considerations in the first part of the work, the second portion of this work will be followed by an empirical study, which explicitly deals with the possibilities and limitations of self-determination in working with people with severe and severe multiple disabilities. The historical change in dealing with people with disabilities as well as the historical development of the idea of self-determination conveys a sense of the need to the issue disabilities and self-determination. Another chapter deals primarily with the legal situation of people with disabilities, but also with the duties and the role of the employees.

The difficulties and necessary conditions of self-determination will be developed in another chapter.

As part of this research, an actual state survey was conducted to determine the level of development of the people with disabilities. As part of an organized setting together with the educational team of the day-care center were drawn up new possibilities for self-determination and consequently attempting to integrate them into the educational life of the day-care center. The evaluation of this project was based on a survey of employees by expert interviews. The analysis of the interviews was conducted in accordance with the guidelines of qualitative content analysis by Mayring.
