Special needs learners with disabilities can have a wide range of skills, abilities and requirements in a classroom. They may have a single disability or condition, or more than one. Disabilities are often grouped into categories, including:
Vision impairment - students who have no vision, or who may see some shapes, color, or light and dark. These students may use a guide dog, a cane or 'sight guiding' (holding the elbow of a support person) to move around safely.
Hearing impairment - students who lack the ability to hear without assistance. They may use a hearing aid, have a cochlear implant, or use sign language or lip reading.
Intellectual disability - these students have a lower IQ (Intelligence Quotient) than would be expected for their age. They may find it harder than their peers to remember, understand, apply reasoning, process information and learn new skills.
Physical disability - students with a physical disability have some sort of mobility limit. They may use a wheelchair or walker, or they may walk unaided but need assistance with movement activities for other parts of their body. Examples in this category include spinal cord injury, cerebral palsy, spina bifida, muscular dystrophy and multiple sclerosis.
Learning Disability - these students have difficulty learning and find problems with memory, information retention and recall and processing of information. There is a difference between a learning and an intellectual disability, and at times a learning disability may not be diagnosed, particularly in an ESL student.
