The Regulations Governing Special Education Programs for Children with Disabilities in Virginia (effective July 7, 2009) defines the term as follows:
“Deaf-Blindness” means hearing and visual impairments occurring at the same time, the combination of which causes such severe communication and other developmental and educational needs that they cannot be accommodated in special education programs solely for children with deafness or children with blindness. 34 CFR § 300.7 (c) (3); 8VAC20-81-10.
