I know what you mean. To me it does seem to have good thought and experience behind it, as gifted people very often have certain traits that can be sussed out without IQ or achievement testing, and that could be useful in assessing giftedness where testing presents problems.
A lot of numbers recorded on various cognitive ability tests may be based on a somewhat subjective evaluation by the tester (e.g. a 0-1-2 point scale for detail given in an answer to a question). Still, testing numbers are obviously going to represent more objective-seeming proof, and just about any decent IQ or achievement test is going to be actually more objective than a Roeper assessment. For these reasons, results from a Roeper assessment might not be worth much for gaining entry to programs, and they also might not do much for a parent but confirm suspicions that a child is gifted.
