I agree that you should begin looking at all your preschool and kindergarten options now because your daughter is going to need accommodations, regardless of the test scores. When it became clear that my then-3-year-old son had already mastered our local public school's kindergarten curriculum, I visited a private gifted-friendly school. The private school not only recommended enrollment there, but also recommended that DS skip a year of preschool and start kindergarten at 4 1/2, which has been an unmitigated success. After hearing just a few things about my son (including that he read spontaneously and fluently at 2), the private school director described the early enrollment decision as "a no brainer" even though DS5 has never gone through any kind of IQ testing. To her, it was just common sense! So, even if early enrollment isn't an option for your DD due to the May birthday, my advice is to trust your gut, forget the IQ score, and start researching your options. If it seems clear to you and any intelligent observer that another year of preschool followed by regular kindergarten is going to be a mismatch for your DD, then it probably is!
