The goals of this study: 1. Determine if a play based test of arm and hand movements is valid and reliable when conducted through telehealth for children with hemiplegic cerebral palsy. 2. Measure differences in parent, provider and child engagement when an assessment is conducted in-person compared to via telehealth. 3. Rate caregivers' overall impressions of procedures when an assessment is conducted in-person compared to telehealth. Participants will attend two visits, one in person and one through telehealth. During each visit, the child will play with common toys. The sessions will be video recorded and scored using two standardized assessments, the Melbourne Assessment-2 (MA-2) and the Assisting Hand Assessment.
