Thanks for posting this. I'd run across some of these articles before but it's good to see them all together. This was one I hadn't seen before and found especially useful:

Understanding Uneven Development
It is important to remember that these children very often do not develop evenly. In fact, young gifted children frequently show peaks of extraordinary performance rather than equally high skill levels in all cognitive areas. The child who learns to read at age 3 or who shows unusually advanced spatial reasoning ability, for example, may not be the child with the highest IQ or the earliest language development. Unique patterns of development can be observed within a group of gifted children, and uneven development is frequently evident in the pattern of a single child. In some cases, it seems as though children's abilities develop in spurts, guided by changes in interest and opportunity. Reading ability, for example, might develop almost overnight. Children who know all their letters and letter sounds by age 2 1/2 may remain at that level for some time, perhaps until age 4 or 5, and then in a matter of months develop fluent reading skills at the third or fourth grade level.
Looks like this needs to be updated on the calendar since the WISC IV is a substantial reformulation of the WISC III:
IQ Testing
The two most commonly used IQ tests with gifted children are the WISC-III and the Stanford-Binet. The Stanford-Binet has a higher range and is the test of choice for highly gifted children. A trained psychologist familiar with the test should administer it.
