I understand your dilemma, but if she is reading mid grade 1 books as a preschooler, even starting SK at the public school for next year isn't really going to do much to solve the academic mismatch. It sounds as if the current school does fairly well at meeting her needs, so if you can at all afford it, I'd leave her where she is for another year. Believe me, sometimes just postponing the problem for a year must be good enough!
It certainly gives her time to develop, gives you time to get to know her better, maybe have another round of testing (though the wppsi is of course out for two years) and may help you see a lot clearer.
I have seen testing go so many ways, from testing our two year old for color blindness, to an ASD eval, to IQ tests almost three standard deviations aoart, it's such a crapshoot...if there is an acceptable placement for SK within your reach, just take it, and then worry about what to do about first grade.
