One of the other benefits of homeschooling, in addition to all the typical ones already mentioned, is that, if you're up for it, you can use it diagnostically. Experiment with different accommodations and adaptations, probe his actual academic and organizational skill levels (wouldn't expect much in the work skills area for a 7 yo!), stop and process any behavior that appears distressed, noncompliant, or disengaged.
You know he won't be behind academically, no matter what you do with him at home for the next few months, so that gives you some freedom to try to tease out the different factors, and also figure out a better fit for future schools/teachers.
