I've just had parents evening at DS3s school. At the same time was a GCSE check in. Y11 pupils were bringing in ID so the right name is printed on their GCSE certificates. While I was waiting I heard several children saying "I don't know" when asked their full name and saw them getting out BC or passports to check. It is a very ethnically diverse school but AIBU to think children should know their full name at the age of 15/16 yo even if they are known by another name?
