This happened before the holidays and DC2 has just mentioned it again.
For a start DC1 and 2 have both been 'over looked' children. They have never been chosen to read (except one line as part of a group) or be more than in the chorus at a plays etc. The same children always get chosen (you know in advance who is going to do the reading in assemblies for parents or be the 'stars' in the plays) - whilst I can see why teachers would chose these children, I don't actually think it fair as it doesn't give the less confident children (if they wish) a chance to become more confident...to show what they can do...I do think they should try and spread it out a bit more - but I have never said this/made any comment to my DCs)
DC1 couldn't care less - had no interest in the attention - so no problem.
DC2 for some reason is much more aware - has noticed and mentioned it in the past. (Why does X always get chosen? kind of way). They seem to want the attention, to want to perform! (but not in a pushy way - they are well behaved in class, not the class clown or anything). My advice was to always try your best, behave and to volunteer if asked - put yourself forward...and if you are lucky you might be. If you aren't it doesn't matter....there is always next time.
From YR1 to Yr3 the choir is made up of all the children, now entering YR4 they had to 'audition'.
DC2 was really really keen - actually likes singing, don't think is terrible (I am, so maybe not the best judge!).
The choir just sing at assemblies etc and do one joint 'all the schools in the area' type of thing once a year -not a competition. I thought the audition bit was just about checking they were keen...would enjoy being in it.
Anyway apparently it is isn't. DC2 was one of 2 children in their class who chose to audition not chosen. When they told me they were obviously upset, putting on a brave face. (A little bit of my heart broke 
) Now they have just asked if I think they will get another chance....when the next auditions will be?
So AIBU to think that at that age for something like this being keen should count just as much as ability? And actually this is a bit shit...
(The teacher who does the choir is known to have favourites in the classroom - initially DC1 was one - was in the choir after being encouraged to audition, but maybe fell out of favour a bit ... do wonder if that influenced this decision too..
.)
