This longitudinal case study examined the communication and literacy learning progress of an 11-year-old boy with severe speech and physical impairments related to cerebral palsy. Theoretically driven literacy assessments revealed unforeseen literacy capabilities. Integrated use of voice-output augmentative communication technology led to improved communication skills as well as increased demonstrations of literacy capability. Systematic instruction addressing the child's weaknesses and strengths resulted in literacy gains across 2 school years.
