This type of behavior by a teacher would be totally unacceptable. You must have documentation. Work with your son to record the date, time of day, class, assignment missing, and other pertinent details of each occurrence. What the teacher did, what the teacher said. How the class reacted. How your son reacted.

Forgetting occasionally may be normal... but on the other hand, have you had him assessed for possible 2e?

1. Document
2. Consider assessment
3. Have him bring his binder home each day and talk him through a sorting process. He may wish to place the date on each paper or worksheet as a way to keep his papers sorted and ready to be turned in.

If such a school may be found, your son may be successful in the short term, but developing executive function skills provides life-long benefit.
