Hi sanne,

You've received great replies above.
I have no insight or advice to offer for getting to the heart of his behavior issues.

For him to keep moving forward with his education, might he take to some form of self-directed unschooling? There are lots of resources to be found by following links in the thread on the "Self-Taught" movie. Although I wrote that thread/post, it was actually puffin asking about deschooling that made me wonder whether unschooling might be a good fit for your son.

Sending hugs.
