I think that at that age the WPPSI is still one that can give you a lot of information. We had to test our kids before 5 for school admissions and they were positive information we got from that. For instance, you can get a sense of relative strengths and weaknesses or realize that she is more well rounded than you thought....

One advantage of the WPPSI is that it is such a commonly used test that schools might be more familiar with it than with others.
