Many thanks, aculady, Cricket2 and Cathy! for your advice!

Met the principal yesterday, but, very disappointed. Before I said, she said, we won't do grade skipping here. No chance! She mentioned all negative side of social skills, and also, in 16 yrs, all other kids got driver licensed, but, your daughter couldn't, she will feel bad, etc, etc...... I just wanted to say,
I don't know how about her 16 yrs old, she is already sad now.

I bought my daughter's NNAT, CogAT score for Grade 1, she said they are really terrific, really, for Kindergarten, but, still, much more K stuff, for example, motor coordination, social part couldn't be tested, needs 1 yr to learn. So, she still needs to be in K, learn K stuff.

The whole conversation was finished in 10 minutes. I prepared some of sample works she did for Grade 2, 3, and even 4. But, no chance to show them. Very upset to see the door is soooo easily and firmly closed.

Maybe, I should try hard to get her class teacher's attention first. But, I tried a couple of times, each time, she just said, my DD is excellent, role model in class, very good. Then, nothing else.

I am new, soft mum to this school system, don't like to be push, but, really, don't know how to get the attention. So much to learn!

Many thanks for all your precious advice!
