ABSTRACT: The influence of early childhood education on sensory integration is essential for understanding how early educational experiences shape children's ability to process and respond to sensory information. This study explores how early childhood education programs influence sensory integration development among young children. The objectives are to (1) assess improvements in children's sensory processing abilities, (2) evaluate the integration of sensory integration activities in early childhood education curricula, and (3) examine changes in children's sensory responsiveness and behavior. A survey design is justified as it enables comprehensive data collection on the influence of early childhood education on sensory integration. A purposive sample of 130 children from preschools in Osun State was used. The case study focuses on a preschool renowned for its sensory integration program. Findings indicated significant improvements in children's sensory processing abilities, the effectiveness of sensory integration activities, and positive changes in children's sensory responsiveness and behavior. Recommendations included integrating sensory integration activities into early childhood curricula and providing ongoing professional development for educators to support children's sensory integration development.
