This may be because I am a teacher myself, but I don't think so.
Took ds1 for his introductory visit this morning. IMO, this should be a relaxed informal affair designed to put small children at their ease.
So, ds1 is happily wandering about, having a go on the computer, looking at a book with me and some other children etc etc.
Then, we are by the literacy corner, she comes over and shoves word cards in front of his face and says, "what does this say, and what does this say", really putting him on the spot. He's a very confident child, but immediately grabbed me and buried his head in my legs - he hasn't done that since he was about 18 months.
As it happens, ds1 has been reading for about 3 months and in a familiar supportive environment can sound these kind of words out (black, sack, dress, mess from what I remember). But jeeeeeeeez, I NEVER grilled any children I taught on their FIRST VISIT in this way.
Rant over.
