BUT TODAY THETEACHER  CALLS MME TO PICK HIM UP, LAST WEEK HE HIT ANOTHER STUDENT  AND TODAY HE THREW SOMETHING AND HIT A TEACHER HE SAID BECAUSE SHE WOULD NOT LET HIM GRADUATE, HE WILL BE ATTENDING ANOTHER HYEAR OF PRESCHOOL. THEN HE WILL GRADUATE.

Did you ask him why he did it before you punished him ? it may be a good idea to get the facts from school and your son ..you say the teacher said he wouldnt graduate ,did you find out why the teacher said that what would have caused her to make that remark to a child ... it doesnt excuse him throwing something but it is showing you there is a problem with interaction at school .My opinion is you find out the reason for his behavior ....
