I agree with you, and if I recall correctly Special Ed teachers might be Medium instead of Light. I taught Special Ed and I know what you mean. Teaching in general is more than Light, I think. As a teacher, I had to move desks, lug supplies, and get up and down from the floor. When you are working in education, you are frequently the only person to deal with whatever situation comes up. My husband is a Nurse and he said as a male nurse, he was considered a human crane!
