Upside: if you do it and get DYS level scores, it was free and you got it done conveniently.
Downsides:
1) school psychs vary tremendously in their abilities. They are considered qualified to do testing-- that is why they are there, as they are typically not certified to diagnose any disorders. Some of them are not great testers or eager to help a child do their very best work. Some are just fine.
2) if the school psych does a WISC, your DS probably can't take another WISC within a year and have it be considered valid. You do want it done right the first time.
Aside: if you want an actual diagnosis on the OT stuff, you likely need an outside professional. Most school OTs can make recommendations and judgments but technically can't diagnose an actual disability. There can be a conflict of interest, as well: often school personnel are under pressure to under-report findings in order that fewer children qualify for expensive services. It is, of course, appalling, but it happens. YMMV.
