Selected subtests of the experimental and revised editions of the Illinois Test of Psycholinguistic Abilities were administered to 30 six-year-old subjects. Correlations between subtests of the two editions were found to be of the same general magnitude as test-retest coefficients reported for the subtests of each edition. It appears that performance on one edition of the ITPA may be compared with performance on the other, and that the two editions may be used interchangeably for some purposes.
