I understand your feelings about the award, it is not meaningful in the sense of recognizing hard work. It does recognize your child's academic talent and especially since it includes Phys Ed and Music.

I would go to support your child. You do not have to make a big deal of it. Having your parents attend school events is often very important to kids. Another reason to go is to show the school that you are an involved parent. This seems silly, but some schools will use it against you if you do not attend.
