Generally it takes between one to two weeks to get to know your students at the beginning of the school year. There are many different personalities. If you get a Master's in Special Education you had better be prepared to teach it.
All school systems are different. Some require an actual degree for a pay increase, while other's go by credits, 15, 30, 45, 60 and then Ph.D. If your system goes by credits, I wonder what would happen if you were one class short of your actual SPED degree?
Over thirty years ago I was sitting at a round table with other staff members. We were going to have a Planning and Placement Team (PPT) meeting, and this was my first meeting. I asked the school psychologist what the post-it note on the child's permanent meant. She laughed as she took it off. It said PITA and she said that she wanted to remind herself how difficult the parents were. (Pain in the ***). Just to be clear I have never ever since that one time saw a note on any child's record!
