Apologies - he was tested with WPPSI. The GLC is the General Language Composite. The way the psych explained it to me was that his Input - what he is learning is very high (152+) but his ability to demonstrate his learning was average. So like when you know the word you want to use but you just cant think of it. She said that if James was tested verbally only he would do very well at school but it is his demonstrated work that is suffering, particularly reading.
I'm not saying that your child has ADHD, but I've heard, over and over, that what ADHD is all about is that the child can't apply the knowledge that the child has. I can imagine that's true of several other challenges. Anxiety sure could block a child from demonstrating what he knows. I think you need to seek more help. In the meantime, it might help to describe the behavior problems and what you've tried to do. What has helped and what hasn't?
While you are waiting for whatever next steps, I can recommend the book, "Transforming the Difficult Child Workbook" by Lisa Bravo. I found with my intense PG/ADHD child that traditional discipline methods made the behavior worse, and this approach made things better.
Best Wishes,
I know how hard it is to have the school folks telling you to fix your kid when your kid is only 5 years old!
