Grammar: schools

We were at an event in a Norfolk school at the weekend. In the main hall was a display featuring a recent school visit overseas and other 'information boards,' featuring lots of diagrams and annotated posters.

Being the curious type I read though the information from start to finish and it was both interesting and illuminating. However, I was also horrified to see so many spelling mistakes and elementary errors in the grammar being used. I suspect there will have been some kind of editing process so this wasn't just down to the children concerned. They will no doubt have submitted their accounts which may well have been used for other materials - possibly online - as well as these front-of-house advertisements for the school: prime real estate.

If teachers or administrators aren't up to standard, how can children be expected to be?
