If you have a decent community college system, then you may want to consider taking writing classes there as well. Many colleges have some online courses available although he may need to come in for exams in some cases. Your DS can take a basic freshman composition course or try something a bit more upper level (with permission from the department) depending on areas of interest. NUMATS also has some online writing classes available and so does CTY although NUMATS has a more affordable fee structure.
Oops, just noticed that this was from last year.
