The presenting issue for us was that DS who used to LOVE SCHOOL started to ask to stay home. After a while, we thought.that something was up. Sure, he had this high scores, but we actually weren't very educated about school refusal and profoundly gifted children. Then all sorts of other academic acting out started. We got him tested andevaluated and it all started to make sense. When he was given higher level work, he stopped complaining about school when he started to attend the fourth grade math class once a week, he started skipping to school. So at this point, honestly, I don't really care about the gaps anymore (if in fact there are any). It's where he needs to be now. If he spends all of next year being a B student, I would be thrilled with that. If he has two months of working hard to make up gaps - fantastic. Because I NOW know that in another year or two we will be right back in the same situation.
