The lesson plans are on the needs of autistic children. The lesson plans are used for special schools and inclusive schools during the orientation period. This research produces learning planning development products through the Universal Design for Learning (UDL) principle for autism at the elementary school level in special schools that are feasible, practical, and effective. The research method used is ADDIE. Analysis of the character and needs of autistic children. Lesson planning is designed according to UDL principles. Development of learning planning through UDL. The result of the research was implemented in special schools dan was introduced to an inclusive school. The pandemic has prevented this research from being fully implemented in inclusive schools. The result of the next study was evaluated. The result of this study indicates that the development of UDL learning planning is considered feasible with a percentage of 82.6%; considered practical with a percentage of 81.6%; and quite effective with a range of n-gain – the value of 0.13 to 0.213. From these results, it can be concluded that the UDL Learning plan is feasible, practical, and quite effective for autistic children in primary schools and quite effective with a range of n-gain – a value of 0.13 to 0.213.
