We got the government ID at the MVA for our 16 yo. He wasn't asked for it once! That said, I would still not risk not having it, especially when it does say "government ID". My TA told me that she didn't believe a school ID would work. I know our school ID's don't have birth dates etc. It was about $15, 1 1/2 hours waiting at the MVA and less than a week to get it mailed to us, so that peace of mind is worth it IMO.
