ABSTRACT Children’s participation and success within the school environment are dependent on developmental and school readiness skills that extend beyond academic skills, including motor, visual, visual motor integration, social, and self-regulation skills. Students enter kindergarten with a varying range of school readiness skills and developmental needs, while teachers may lack the time, support, or ability to address them. A pre-test/posttest design was used to deliver a Universal Design for Learning approach to teacher education on motor, visual, visual motor integration, social, and self-regulation skill development to 12 kindergarten and first-grade teachers using an occupational therapist-teacher collaborative teaching model. Additionally, this approach facilitated opportunities for teachers to integrate skill development within their classrooms. An author-generated survey was used to capture teachers’ self-reported confidence and knowledge of skill development. Comparing pre- and post-survey scores, using the Wilcoxon Rank Test, indicates that the method used in this study has a statistically significant effect in increasing teachers’ knowledge of developmental skills and confidence in providing classroom interventions to support student participation. These results support Universal Design for Learning’s effectiveness in supporting children’s developmental skills through occupational therapist-teacher education.
