This paper aims to show the effects of actions focused on supporting the development of children with Autistic Spectrum Disorder (ASD). Conducted with an eclectic approach, these actions sought techniques tailored to the individual person and their problems. Children aged 5-7 years underwent a two-stage diagnostic procedure (preliminary and final) using Schopler's Psychoeducational Profile (the PEP-R test). Between these two measurement points, they participated in a year long development support program using sensory integration stimulation techniques, fine motor skills stimulation, and dog therapy/animal-assisted therapy. The results obtained in each case attest to the applied proposals' effectiveness yet do not allow for general conclusions to be reached. However, they can be a prerequisite for conducting a broader research project and developing personalised early intervention programs for children with ASD.
