We can sometimes have a skewed perspective around here about what "gifted" is. I would say that her WISC scores show a PRI that is probably in the range that would be considered gifted by your school district. (All of the subscores are in the "superior" range.)
Are there any language or hearing quirks in her history or any issues with the testing conditions that could have interfered with her understanding and depressed her verbal scores? (Examples would include bi-lingualism, ear infections, speech or language delays, autism spectrum conditions, hearing impairments, a tester with an unfamiliar accent, noisy testing conditions, etc.) It would be unusual, but not impossible, for a child who learned to read at 3 without formal instruction to have a VCI that was only in the average range unless there was something else going on either with the child or the testing conditions.
