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.
