I have 2 ds's at the same school. Both work hard at school. DS2 is more of an all rounder academically but DS1 does have great ability in 1 subject.
So far this year ds2 has received 7 Head Teacher's Awards and DS1 none. In fact DS1 has only receive 3HTA's in all. (now year4)
Makes me feel that there is a real inconsistancy in individual teacher's approach to the awards and does in some ways devalue the one ds2 received.
