Honestly, whether DYS accepts the SB-IV or not is a side point to me. When testing, I'd think that the point would be to get the most accurate representation of the child's abilities as possible. I realize that IQ tests are imperfect and no test is going to give you the be all end all of who a person is, but I also can't imagine intentionally choosing an old test when the newer version has been out for many years b/c the scores just wouldn't be as accurate.
There are places that still use even earlier versions of the SB. It is controversial, though, and I'd always go with the most recent version unless there was some compelling reason to select an older version. I also believe that the most up to date test would be best for advocacy purposes.
