Hearing the word disability can make it difficult for a person with a disability or someone in his family to feel hurt. Therefore, the word 'disabled' is used instead of the word 'disabled'. According to government policy, there can be four types of disabilities or people with special needs: orthopedic disabilities , visual impairments , deaf-mute disabilities , and mental disabilities. Each type of disability is further divided into four categories: mild (less than 40%) , moderate (40% and above but less than 75%) , severe (75% or more) , and severe (100%).
