I'm sure this question has been asked and answered many times before, but I'm wondering when you should start testing your child in general.

DD4 has been in preschool this year -- a Montessori-like pre-k that has been really good for her. She has perfectionism issues and will often not even attempt to write letters, but school has helped with that. She will go to pre-k next year (she just turned 4 in January) and then off to school after that.

She began reading at age 3 and now reads at a 1st-2nd grade level at least (I'm not sure about reading levels so if anyone has any resource for this, that would be great). She does simple math problems. Her memory is unbelievable and she learns VERY quickly.

I know it's a little early since she still has another year of preschool ahead of her, but I think it would be best if DD skipped K when the time comes. I'd like to start preparing myself now if possible. What test is usually required for this? This is unknown territory for me since DD4 is my oldest. I was thinking of contacting the local university to see if any graduate psychology students could administer a test for free -- anyone have experience with this?

I probably wouldn't test until she was closer to 5-yrs-old since from what I've read, it seems the older the child, the more accurate the results. And I don't want to test too soon before Kindergarten. However, if I can get some graduate psych students to administer a free test, I thought about having it done a couple of times so DD can get comfortable in that situation (she gets shy about reading/writing/math in front of others and I fear she'd score low because of this).

Any thoughts, comments, suggestions??

Thank you!
