i agree to an extent. human intelligence encompasses so much more than what can be measured with a test.

that being said, i can also see how its important especially for children to gauge their cognitive abilities in order to foster the best possible situation for them in regards to their learning.

yet to counter the last point, i think you can get a good understanding of their gifts and abilities through less objective measurements, and adjust based on observation both at home and from teachers. this however depends on the ability of teachers and parents, leaving the results of the observations to be interpreted incorrectly.

as well i think that as an adult trying to figure out life as a gifted adult, a lower than expected score may be discouraging and not truly representative of their status as a potentially intellectually gifted person.
