A Comparison of an Achievement Battery with Two Tests of Ability with Educable Mental Retardates. Final Report.
MacKinnon, Ronald C.; Elliott, Charles
To find the concurrent validity of two scholastic aptitude tests when a scholastic achievement test was used as a criterion for use in placement of mentally retarded children, 127 subjects were involved. The California Achievement Test (CAT) was used as a criterion measure, and the Primary Mental Abilities test (PMA) and the Slosson Intelligence Test (SIT) were used to determine the correlation of the scores with the criterion measure. The results indicated correlations of .68 between the PMA and the CAT and .62 between the SIT and the CAT. The intercorrelation of the PMA and SIT was .67. Ability subtests were analyzed to determine their correlations to the criterion. The conclusion was that when six or more children are to be tested, less time if needed and no concurrent validity is lost by using the PMA rather than the individual test, the SIT. Tables of results are included. (Author/JM)
