What is the general term for schools for mentally retarded children?

Schools for children with mental retardation usually don't use this name directly, so what is the general name of schools for children with mental retardation?

Schools for mentally retarded children are generally called schools for mentally retarded children. A school for mentally retarded children, as its name implies, is a place for children and adolescents with mental retardation (referred to as mental retardation) to study, and it is an institution that implements special education for mentally retarded children and adolescents. According to the characteristics of children with intellectual disabilities, we should teach and train them, compensate their intellectual and adaptive behavior defects, and cultivate them into workers who can adapt to social life and earn their own living.

In addition to teaching students in accordance with their aptitude, the school also provides some "protection", which can make these disabled children have a conditional self-protection even if they don't understand the reasons, and help them grow up healthier and safer in their later lives.
