A communication disorder may be evident in the processes of hearing, language, and/or speech.” The IDEA label for students with communication difficulties is speech and language impairment and they are eligible for special education if they have “a communication disorder such as stuttering, impaired articulation, a language impairment or a voice impairment, which adversely affect a child’s educational performance.”
