There are essentially three types and prospective classifications of students with disabilities, Type or Level 1. Those who perform equitable with or better than mainstream students, but have personality disorders and/or behavioral issues, Type or Level 2. Those who do not perform equitable with or are incapable of learning at the pace of mainstream students, and have personality disorders, and Type or Level 3. Those who are incapacitated or have other physical disabilities (i.e. cerebral palsy, blindness, etc.).
Traditional Type or Level 1 students with minor speech impediments should be placed in mainstream classes, where they would benefit from interaction with normal students. Just as one obliviously acquires an accent when moving from one city and/or state or country to another, students with minor speech impediments would be more likely to mimic the speech patterns of mainstream students with whom they would attend classes.
Braille and sign language should be incorporated into the curriculum for students who are blind and/or deaf, and Level 3 SpEd instructors should be required to know sign language and have some familiarity with braille.
Pediatric Neurosurgery & Other Corrective Options for Incapacitated Students
Level 3 SpEd students with conditions like cerebral palsy should be referred, with parental and/or guardian consent, for assessment and prospective corrective treatment, i.e. neurosurgery, Hip Abduction Orthosis, etc.,* to synonymous medical treatment facilities, ideally those that are connected with local colleges or universities.
