My research focuses on the special educational support and accompaniment of individuals with severe, profound and multiple disabilities and high support needs. Additionally, my research examines educational units providing developmental education and training for school-age learners with severe, profound and multiple disabilities in Hungary. This work is based on identifying pedagogical, special educational, and instructional methods, tools, opportunities, and good practices that can be applied throughout the entire educational process. I investigate the pedagogical and special educational approaches, methods, and good practices currently employed by professionals working in special education institutions that provide developmental education and training in Hungary.
