Glad that we could overcome that communication difficulty and sorry for causing it. Yes, I do feel sorry for the kids. Sorry also to Steve for misreading your message (as I am sure I did). Anyway, moving on - or back - to the original question from A Dorset Parent ...
My daughter did an NFER practice paper today (from Letts), and it featured precisely the use of single quotes A DP described. This was the multiple-choice version of the paper, and from the answers provided in the pack, it was very clear that the use of single quotes was NOT intended to be erroneous
I have no idea how safe it would be to extrapolate from this NFER practice paper to real tests. Do NFER set all 11+ tests these days?
(My daughter, it turns out, has also been taught this idea that speech marks are double and quotation marks are single. So my usual advice, 'when in doubt, stick to what you have learned at school', could be the worst possible advice in this case
. Fortunately, the way that the test is presented meant that she knew there could only be one error in each fragment and there were enough other errors for her not to be misled into marking all the places where single quotes were used. It shouldn't be like this
