Models of Disability• Medical Model
– Disabled people are patients who need treatment and/or cure.
• Education Model– Disabled youth need special education.
• Rehabilitation Model– Disabled people need assistive technology and training for
employment and everyday life.
• Legal Model– Disabled people are citizens who have rights and responsibilities
like other citizens. Access to public buildings, voting, television, telephone, and education are some of those rights.
• Social Model– Disabled people are part of the diversity of life, not necessarily in
need of treatment and cure. They do need access when possible.
