GATB LONGITUDINAL MATURATION STUDY.
DROEGE, ROBERT C.
THIS ARTICLE DESCRIBES RESULTS OF THE FIRST IN A SERIES OF THREE LARGE-SCALE LONGITUDINAL STUDIES CONDUCTED BY THE U.S. EMPLOYMENT SERVICE TO INCREASE THE USEFULNESS OF THE GENERAL APTITUDE TEST BATTERY (GATB) FOR COUNSELING HIGH SCHOOL STUDENTS. THE FINAL SAMPLE CONSISTED OF 26,708 HIGH SCHOOL STUDENTS. ALL WERE TESTED WITH THE GATB IN 1958, AND THOSE IN THE LOWER HIGH SCHOOL GRADES WERE RETESTED IN THE 12TH GRADE. RESULTS WERE AS FOLLOWS--(1) STABILITY COEFFICIENTS WERE HIGHEST FOR THE 11TH-GRADE SAMPLE AND LOWEST FOR THE NINTH-GRADE SAMPLE, (2) INTERVAL BETWEEN INITIAL TESTING AND RETESTING HAD VERY LITTLE RELATIONSHIP TO SIZE OF PRACTICE EFFECT, (3) MATURATION INCREASES WERE LARGEST BETWEEN THE NINTH AND 12TH GRADE AND SMALLEST BETWEEN THE 11TH AND 12TH GRADE, AND (4) OCCUPATIONAL APTITUDE PATTERN STABILITY WAS INCREASED THROUGH USE OF A "BAND" AROUND THE CUTTING SCORES. THIS SPEECH WAS PREPARED FOR THE AMERICAN PERSONNEL AND GUIDANCE ASSOCIATION CONVENTION (WASHINGTON, D.C., SESSION 231, APRIL 7, 1966). (JH)
