I don't have answers, but I'm sure you'll soon get many.
Also in case [2], what if you wait (for two years?) for the score to "expire"?
22B, as I understand, every IQ test is administered differently - they have different subtests and may be different types of questions. So, if the score in a WPPSI is not great, one need not wait for "test expiration" - one could just go ahead and get another kind of test like Stanford Binet, WISC etc if they are confident that the issue was with the tester or the child having a bad day etc and that the results were not a true reflection of the child's abilities.
BTW/ when we took the WPPSI, the psychologist told us that we could not take the same WPPSI for a year. But there were no restrictions on taking other types of IQ tests.
