Identifying a Nonverbal Aptitude Measure for Use in Counseling Secondary Level Mentally Retarded Pupils.
Vermont State Dept. of Education, Montpelier. Div. of Vocational-Technical Education.
One hundred forty students (mean age 17.5 years, mean full scale IQ 69.18, and mean reading grade level 3.61), in the Diversified Occupations Programs (Vermont) were investigated to determine whether the Nonreading Aptitude Test Battery (NATB) is a valid instrument for identifying occupational aptitudes of educable mentally retarded and low average students. Findings for six hypotheses indicated: (1) that a positive relationship existed between the number of occupational aptitude patterns (OAPs) obtained on the General Aptitude Test Battery (GATB) and the NATB; (2) that the mean number of OAPs identified by the NATB was significantly higher than the mean number of OAPs identified by the GATB; (3) that all aptitude scores (on both tests) except on clerical perception were significantly related to full scale IQ; (4) that there was no difference in relationship between verbal IQ and cognitive aptitude scores by students on both tests; (5) that there was a positive relationship between performance IQ and all aptitude measures of the GATB and NATB with the exception of the clerical perception and motor coordination measures; and (6) that there was a significant relationship on both tests between reading score measures and aptitude scores for intelligence, verbal ability, numerical ability, and motor coordination. The findings implied that counselors and placement officials for retarded and borderline students should seriously consider selecting the NATB over the GATB. (Included in appendixes are items such as descriptions of the tests, definitions of aptitudes measured by the tests, and statistical data.) (MC)
