Children with disabilities are born with the freedoms and rights that belong to all human beings. The paper deals with the procedure of expertise of children with disabilities. It is a procedure based on which children exercise their rights from different systems. The expertise of children with disabilities provides professional and detailed insight into the degree of physical impairment of the child and his functional abilities. For children, the findings and opinion of the expert examination procedure are not final, and the same procedure is repeated as a control examination due to their chronological age and possible overcoming of developmental difficulties in the hope of better functioning of the child in the future. Expertise is one of the steps in improving their quality of life and overcoming weaker initial chances. The aim of this paper is to give an overview and present the importance of the expertise procedure for children with disabilities using existing relevant documents, strategies, legislative framework and research conducted by the method of semi-structured interview for the purposes of this paper. Based on the acquired knowledge, it is possible to conclude multiple changes. These are the improvement of the expertise system by adopting new legal regulations, the adoption of a standardized list of physical impairments and functional abilities, and the education of experts who carry out the expertise procedure. The obtained insight into the whole procedure clearly indicates further needs for improvement in terms of increasing transparency, networking of institutions, better flow of information, which would significantly speed up the whole process of expertise.
