Well, you can see that there can be very little opportunity for your child to show what she knows and is capable of unless you can get them to pay attention and actually test her.

DS' K teacher didn't realize he could read because there was just no chance for him to show her. She had no idea he was doing 2nd grade math at age 4. In K, they were still counting and sorting and identifying shapes. Several kids in his class didn't even speak English...
