The results raise questions concerning test selection for diagnosing intellectual disability and the use of the correlation statistic for comparing intelligence tests. Compared to similar measures, the RIAS-2 is faster: all eight subtests can be completed in less than an hour; the screening measure (the RIST-2) provides a g score in less than 15 minutes. (Colin Elliott, 1983).
