My son has been recently identified as gifted. Testing was requested by us due to behavior problems last year in grade 3, which we suspected was a result of restlessness/boredom. In grade 4, he is in a much more supportive environment for his learning style/needs. We do not have a program in my state. The school psychologist (with agreement by his teachers) tells us that he is a good candidate for grade acceleration (4th to 6th). Everyone I speak to about it immediately thinks it is a bad idea due to maturity. I do not quite know how to gauge this issue. How do you determine maturity at age 9? In some ways he is like every other kid his age, but in many, many ways he is way above..a big one being humor. He is very well liked by his peers, but has few close friends. He is awesome with younger kids (as a teacher to) and adults find him hysterical (most kids his age don't get his jokes). Any thoughts??
