The chapter focuses on the needs and professional demands of teachers working with children with disabilities. The authors solve the problems set in the research task by (1) systematizing approaches to identifying the needs of teachers in training; (2) building a theoretical-level model of identifying educational needs based on the study of samples of modern lifelong pedagogical education; and (3) comparing various techniques and principles. The authors analyze strategies for collecting and implementing educational needs in different countries. Moreover, the authors single out the main sources of educational needs from the position of a competence approach in lifelong education. These sources are (1) individual professionals, (2) educational organizations, and (3) education as a public institution in general.
