Classes are usually of between 5 and 10 children. You will teach regular lessons to the whole class or small groups. There is an aide who knows the children and will give you a great deal of support and help during the day. Classes are small allowing you to spend time with each child. Not the 2 minutes a day of individual time which a child in regular class can hope to receive.
Many special classrooms have sophisticated behavior monitoring devises tailored for each child.
Children enjoy coming to class because they get special support. Many behaviors that they display in regular class will not surface. You will have fewer distractions during the day which will make your teaching day more relaxed. Why don't you check that box which gives you the option to work in special needs classes.
