The Validity of the Nonreading Aptitude Test Battery for the Mentally Handicapped

Abstract

This study showed that the mean number of Occupational Aptitude Patterns (OAP's) generated for a sample of 140 mentally retarded and borderline intelligence students was significantly greater for the Nonreading Aptitude Test Battery (NATB) (7.10) than for the General Aptitude Test Battery (GATB) (3.70). A Pearson product moment correlation coefficient of .846 showed a positive relationship between the number of OAP's identified by the two tests. A summary is also given of the observed correlations between selected GATB/NATB subtest scores and the full-scale Wechsler Intelligence Scale for Children, the Stanford-Binet Intelligence Scale, and the reading comprehension subtest of the Peabody Individual Achievement Test.
