I know this is a minor problem to be dithering over, so bear with me 
DD came home with a selection of certificates at the end of Year 7 - I'm very pleased and proud of her, she's worked hard despite finding the transition difficult, lots of 'always tries her best' in her end of year report.
When she was in primary, we always stuck any certificates up in the kitchen for a while after being awarded, so I feel like I should do the same with these. It just feels a bit odd - in primary it was always 'golden certificates' and they were given out for things like improvement at something the pupil struggled with, acts of kindness, etc. These are straight academic achievement (best in year at thing X), and somehow it seems different - ie partly about luck as well as working hard. But then if I went to someone's house I wouldn't be at all surprised to see a sports trophy or a music award out in the kitchen, and being sporty or musical is also a mixture of effort and talent . . .
