A student with deaf-blindness is one who has a combination of severe hearing and visual losses after best correction and is determined to be eligible as auditory impaired and as visually impaired according to the specific eligibility criteria for each of these disabilities.  If an eligible student with a visual impairment has a suspected hearing loss that cannot be demonstrated conclusively, and if a speech/language evaluation performed by a certified speech and hearing therapist, certified speech and language therapist, or licensed speech language pathologist indicates there is no speech at an age when speech would normally be expected, the student may be eligible for services as deaf-blind.
