Fine motor performance skills are essential for children's successful educational participation. Kindergarten curriculums are increasingly academic with less emphasis on play-based learning. Increased expectations for kindergarten readiness do not align with developmental milestones. Occupational therapists are uniquely positioned to support students and teachers with preparing for kindergarten. This six-week collaborative intervention utilized fine motor and sensory activity centers, integrated within the classroom, to promote kindergarten readiness for 16 preschool students. Pre- and post-testing indicated clinically significant gains in readiness skills. Results of this pilot study support the effectiveness of integrating occupational therapy within the preschool classroom to improve kindergarten readiness skills.
