Speech-Language Pathologists/Therapists specialize in the various aspects of communication including articulation, language, fluency (stuttering), and voice. In the educational setting, the determination of a speech impairment is based on the presence of a communication disorder that adversely affects the educational or functional performance of the student. The ARD committee, including the Speech-Language Pathologist/Therapist, determines if the student meets the eligibility criteria for speech-language impairment and if the student requires specially designed instruction by a speech-language pathologist.
