The Cattell Culture Fair Intelligence Test (like the Raven's Progressive Matrices) is not completely free from the influence of culture and learning. Some
high-IQ societies, such as The
Triple Nine Society, accept high scores on the CFIT-III as one of a variety of old and new tests for admission to the society. A combined minimum
raw score of 85 on Forms A and B is required for admission. The tests are used by many including
Mensa and
Intertel, which offer a place in their society to anyone scoring in the top 2% and in the top 1% IQ scores respectively.
Validity Direct concept validity Direct concept validity (sometimes called
construct validity) refers to the degree to which a certain scale correlates with the concept or construct (i.e., source trait) which it purports to measure. Concept validity is thus measured by correlating the scale with the pure factor and this can only be carried out by performing a methodologically sound
factor analysis. The relatively high loading of the Culture Fair Intelligence Test on the fluid intelligence factor indicates that the CFIT does, in fact, have a reasonably high direct concept validity with respect to the concept of fluid intelligence. The Culture Fair Intelligence Test was found to load more highly on a "General Intelligence" factor than on an "Achievement" factor, which is consistent with the concept that the CFIT is a measure of "fluid" rather than "crystallized" intelligence.
Convergent validity Convergent Validity is the extent to which the Culture Fair Intelligence Test
correlates with other tests of intelligence, achievement, and
aptitude. The intercorrelations between the Culture Fair Intelligence Test and some other intelligence tests have been reported, as shown in the Table below. == See also ==
