No, I definitely wouldn't - and tbh, if my son were still sad about school's lack of acknowledgement two months later, I'd be very concerned, and would be talking to him about valuing experiences for their own sake and not because of someone else's approval! In my experience schools' acknowledgement or not of children's achievements appears random (while some of my DS's have been acknowledged, most haven't, and the ones that have been noticed haven't been the ones that were most prestigious!). I suspect it basically is a random process, possibly influenced by school ethos, who happens to mention it to someone who controls recognition and when, whether the child is perceived as needing the boost, etc. etc.
