Disorders from the spectrum of autism, that is, PSA belong to a group of neurological developmental disorders that are manifested in the uniqueness and deviation from social interaction, behavioral, communication, interest possibilities of the child, and later of the adult. People with PSA have difficulties in understanding social interactions, and difficult situations occur in individuals with pronounced non-verbal communication and difficulties in maintaining interpersonal relationships. In addition to difficulties in expressing their own emotions, people have difficulties understanding the emotions of other people. Group functioning is impaired by having restrictive interests and obsessions with one topic. Repetitive behavior is often present, where the person constantly repeats certain actions such as tapping, walking in circles or turning the same object. Also, reduced or increased sensitivity to sensory stimuli such as tastes, touches, smells, light or sounds is possible. An exceptional difference is also present in the reactions of sensory processing ranging from hyposensitivity to hypersensitivity. Based on the law, it is possible to include children with PSA in the system of regular early and preschool education, in which educators play a key role. Everyday work with children tries to properly approach difficulties and focus on interactions with peers and learning skills useful for everyday independent and community life. The goal of the final paper is to present the diagnosis of disorders from the autism spectrum and to describe the used structured and semi-structured programs implemented in the field of early and preschool children. The information is based on a search of scientific databases using the systematic review method. It is the teachers who are in charge of creating the best environment, helping to adopt routines and predictable activities. The approach to each child is individual and depends on the individual needs of the child. By applying professional knowledge, one tries to act in accordance with the maximum interest of the child and to establish verbal communication, but also to master the social skills necessary for interaction with peers.
