Four research papers on the evaluation of the Utah State Department of Employment Security's (USES's) General Aptitude Test Battery (GATB) for the deaf are presented. The studies were conducted by the test research staff of the Employment Security Commission of North Carolina from 1970 to 1979. The studies contain not only the analyses on which the GATB for the Deaf in based, but discussions of the issues that prompted the studies and the chronology of steps taken to resolve these issues. Report titles include: (1) "The Development of GATB Administration Procedures for the Deaf"; (2) "Technical Report on the Development of Revised GATB Instructions for the Deaf"; (3) "Technical Report on Aptitude Scores of Deaf High School Students on the General Aptitude Test Battery and the Nonreading Aptitude Test Battery, July 1971"; and (4) "Technical Report on Aptitude Scores of Deaf High School Students on the General Aptitude Test Battery and the Nonreading Aptitude Test Battery, Study II November 1972." The GATB appears to be more valid for deaf examinees than does the Nonreading Aptitude Test Battery. The study reports recommend the use of trained interpreters in administration of the GATB to deaf individuals. While this method is somewhat superior, a more practical method of testing for most job service agencies involves the individual administration by staff not necessarily trained in manual communication.
