Their minimum IQ is 125, although entrance is fairly competitive and most students score significantly higher.
If all they are looking for is a 125, and your son is mature enough to sit still and answer 'dumb questions' for the time needed, then my guess is that he should have no problem. It's hard to score a 150 on the WPPSI by age 5 because of ceiling issues, but a 125 should be fine.
If he doesn't get the 125 from the school, can you go back and get private testing afterwards?
If it's competitive, do he get an advantage by going as a preschooler - if so - take it!
Enjoy the difference!
