ditto pb and other PPs.
I would consider that you already have achievement data that suggests some kind of unusual learning profile (one that may or may not technically tip into learning disability range, but likely has some effect on her learning experience). You've noted that she is performing exceedingly well in mathematics, barely above average in reading, and has a history of early strength in verbal and fine motor skills. I will include the caveat that, with largely self-directed learning, she may have advanced more in some subjects because of personal interest, not because there was actually a difference in rate of learning between them and her less-advanced subjects.
But let's assume (a big if) that these achievement scores accurately represent her skill acquisition in the different areas under equivalent conditions of access to instruction. With that assumption, the math strength and reading relative weakness might suggest some unidentified impediment to learning to read (e.g., dyslexia). We don't currently have enough information to answer this question one way or the other, but I think we do have enough to suspect that it's a question that it might behoove you to ask.
The specific weakness in information found on the WPPSI doesn't necessarily concern me as much per se, as it's highly dependent on cultural context and access to typical English-speaking first world experiences, which may not be a reasonable assumption even for a child in an educated, high-SES family, if they have a family culture which is significantly different from the majority. I will note that, if her oral language is strong, but her reading is only age-appropriate, I would not be that surprised to see a relative weakness in Information, where this subtest is closer to age-appropriate, rather than above average, because the difference between the testable information available to a NT kindergartner and a high-cognitive one often hinges on the latter's much more advanced access to text.
I'll echo others in saying that it would be much easier to provide feedback on the test profile with subtest and index scores, but please don't feel pressure to post them, if you don't feel comfortable with doing so. I also don't mind responding to a pm.
