Most schools around the world use inclusion, which means children with special needs, need to earn their right to be in the regular classroom. Sometimes schools may use full inclusion for certain students such as those with mental retardation. In that case, this is where social tolerance is afforded rather than if these students actually do earn their right to be in regular classroom. Sometimes mainstreaming is used, this is when children with special needs are in regular classroom settings as much as possible and put in special classes for the rest of the day. Social integration is used for students with special needs who are in a resource room or other special class for the rest of the time.
