What are my options if my 18 year old type 1 diabetic son is being denied his high school graduation and diploma due to attendance issues (high blood sugars), even though he has 5 A's and 1 B for final grades? He has awesome teachers and awesome grades but this is coming from the principal. Principal did not want to even look at my son's blood sugar logs or his glucose meter readings, etc this morning when I met with him. That was the 1st time I've ever talked to him, and he wants to 'teach my son a lesson' and 'is not into making exceptions'. Any advice is greatly appreciated.
