Leiter R vs WPPSI with 3- and 4-year-olds

[Laura Morett]

If you only need a nonverbal measure, another option would be Raven's
Progressive Matrices, which has been used successfully with nonverbal
populations (autistics).  I believe there is an age-appropriate
version that is part of the WPPSI, but you may also be able to
purchase it separately.  I'd suggest that or the Corsi Block test if
you are only looking for a measure of non-verbal intelligence.

Regards,
Laura Morett
