I took DD2 to her interview for pre-school where she will go from September (age 3 and 7 months - this is pre-school and not reception!). She is a cheery, sunny little thing, and was only a little bit fazed by being talked to (at?) by a strange woman in an office. The headmistress started off by asking her her name, how old she was (3 last week), if she could draw a number 3 (she could), how old her sister was, her sister's teacher's name, if she could count to ten, what she liked doing at playgroup. She answered all the questions really fluently and in sentences (and counted to 10 in French too for good measure - no idea she could do that!), sang "Twinkle Twinkle" fairly tunefully. I was so proud of her, and all the headmistress said at the end was "She can't say her Ls. You'll have to keep an eye on that in case it develops into a speech defect!" She didn't thank my daughter or say she had been good or anything positive. DD1 could barely string three words together at 3 (and also couldn't pronounce her Ls), but was cheered through the interview by the previous head. I don't see the point of interviewing such young children, personally, but if you are going to do so, make it a positive experience!
