Special education, which is also known as special needs education, is a very important way to address students with educational challenges.  
Yes, my daughter has special needs. It must be hard to do that job
Yes, it certainly is.  Especially when one considers that the arrangement of teaching procedures, the adapting of equipment and materials, etc., are all planned and systematically arranged for each individual.
I would think another challenge of special education would be that every child is different in their needs.
Yes, exactly.  Interventions like these are designed to help each individual with special needs.  Such interventions are not provided in a typical classroom education.  It is very important.  
This country would be in bad shape if there weren't special education teachers. Do you know any other good information about them?
Special education programs became mandatory in 1975.  The United States Congress passed Education for All Handicapped Children Act (EAHCA).  It was in response to education problems in the public school system.  
Well that's good the government ensure that everyone's needs are addressed!
