It's difficult to measure creativity, but this is about as good as it gets, even though it's one of the older tests. It does have a fair amount of research on it, including longitudinal studies tracking adult creative products. Generally, it is considered to be a good supplementary instrument, for including additional students into advanced programs (especially those from underrepresented populations), but not as an exclusionary instrument. That is, a student who doesn't perform exceptionally on a cognitive or achievement test (e.g., WISC, ITBS), but does on the Torrance, should be considered for inclusion in gifted programming, but a student who does well on cognitive or achievement testing, but not exceptionally well on the Torrance, should not be excluded because of the Torrance results.
There is discussion as to the value of interpreting the different scale areas, versus the composite score, with some support for one, two, or three factors.
