People with invisible disabilities face specific challenges that are often overlooked when analyzing the bias that people with disabilities experience. They may encounter misunderstanding, judgment and stigma. They may not be believed or feel they have to justify their disability. They also may not get the proper diagnosis of their condition or the accommodations they need. This lesson provides an opportunity for students to learn more about invisible disabilities, reflect on the bias and other challenges people face and analyze school-based scenarios that involve students with invisible disabilities.
