Art has a significant impact on children with developmental disabilities. Each area of art in some way affects the development of those children. The art of music helps improve language skills as well as improve social interactions and sensory integration. Dancing, which helps with motor development and emotional problems, is one of the aspects of the art of music. Arts such as painting and drawing provide children with free and independent expression, as well as helping them to develop fine and gross motor skills. Through performing arts, children can develop their imagination, communication skills and social interactions. All the areas of art mentioned above are also utilised in the context of therapy. Art as therapy provides therapists with the opportunity to focus on the child's comprehensive development as well as an individual approach with each child and focal point on a specific difficulty. Therefore, art is a valuable tool that provides support to children with developmental disabilities and positively influences their development. The point of the paper is to research how art can improve developmental skills and the quality of life of children with developmental disabilities.
