Did I miss something, or did you say that he was three? Three year olds play, to learn at their age, and if I were three, I think I would be mad and sad if I had foreign laguage time too.
If you need day care, find one that is play based and fun where he can master developmentally appropriate english lagnague skills, social skills, and plenty of positive reinvorcement for things that he can do at his age and skill level. If you don't need day care, he will be ready for kindergarten if you have him at home, read to him, play with him, talk to him all day long about everything and anything, and enrich his everyday enviornment. You will give him a great start and he will learn all the skills he needs if you just include a few regular play dates to socialize.
Nothing he is doing is developmentaly inappropriate. What surprises me is that the other kids can do what this preschool is expecting, which is just freakish and not going to help one of those kids be a genius if they are not going to be a genious anyway. What a waste. I would get my child out of any insistution that though it was in anyway helpful or appropriate to speak to a three year old like he was a little adult. That director has no clue what makes kids tick, and I would not leave my child in a school under her direction for another second.
Find some thing fun, something developementally appropriate, and let him be a success.
