great news, I guess they usually administer some sort of test to confirm his level. So my guess is they are going to ask your permission.
In our case, DD, then 5 was given IQ and ability tests and advised to skip a grade (K)and we also felt comfortable in doing that
so she did skip a grade and doing well and enjoying her time.
You know your child best and decide based on their recs. one does not have skip grades to show smartness, just my opinion. occasional boredom in class should not be the deciding factor either..........
best of luck
