There are people who will take your money, if you want to have her tested - but honestly, there's no point (and testing at this age is pretty unreliable anyway, and if you wanted figures to use for school or for DYS application you'd need to retest when she was older anyway). You know your daughter - go and visit the possible preschools and think about how she'd be there, and choose a place where you can imagine her being happy.
If you have a look around the archives you'll find many threads on preschool environments. What quite a few of us have found is that the *less* the place does that is academic, the better - if they aren't doing letters at all, or do them for two minutes a day, it doesn't matter if your child has known them for years and the others are just learning them, whereas if they regularly have children sitting down doing school-type work, disparities can cause more problems.
