Basic competences for work in the educational context are gained by three-year and five-year university undergraduate and graduate studies. Further education of preschool teachers are covered by the variety of professional trainings, mostly through profesional workshops and seminars. The competences that a preschool teachers gain during lifelong learning is a set of various knowledges, abilities, skills and attitudes, through which they build their practice. When it comes to the competencies of preschool teachers, they are particularly important in the context of inclusive education. Besides the key competencies for working with children with disabilities, specific competencies are also needed. A set of specific competencies preschool teachers gets through professional seminars intended for preschool teachers to work in such an environment. Inclusion is the pedagogical connection of disabled children with children without difficulties, and implies a higher level of respect for children with developmental difficulties and treats them as equally equal participants in the educational process in order to enable them to participate equally in the educational process. The preschool teacher is a key figure for successful inclusion because it provides the basis for further integration throughout life. The aim of this paper is to identify the phenomenon of lifelong learning programs, which would further encourage preschool teachers to work with children with disabilities. The research was carried out through an analysis of the available content of lifelong learning programs at the Education and Teacher Training Agency and in the faculties for teacher education in the Republic of Croatia. The research has shown that the number of professional seminars intended for preschool teachers working with children with disabilities is decreasing, while the need for them is increasing, thanks to strategies on inclusive education in European Union and Republic of Croatia.
