DEVELOPED TO AID MANAGERS OF DATA-PROCESSING CENTERS AND PERSONNEL DIRECTORS IN SCREENING PERSONS WITH APTITUDES FOR COMPUTER PROGRAMING, THE COMPUTER PROGRAMMER APTITUDE BATTERY (CPAB) INCLUDES DETAILED DESCRIPTION OF TEST ADMINISTRATION, INTERPRETATION, DEVELOPMENT, AND STATISTICAL INFORMATION. FIVE SEPARATELY TIMED TESTS (VERBAL MEANING, REASONING, LETTER SERIES, NUMBER ABILITY, AND DIAGRAMING), ARE PUBLISHED IN A REUSABLE BOOKLET AND ANSWERS ARE RECORDED ON A SELF-SCORING SHEET. IF LOCAL PERCENTILE NORMS ARE NOT AVAILABLE FOR PARTICULAR ORGANIZATION, CPAB PROVIDES NORMS AND GUIDELINES FOR SCORE INTERPRETATION. RESEARCH IS CITED IN SUPPORT OF THE CPAB--RELIABILITY COEFFICIENTS, TEST INTERCORRELATIONS, AND UNIQUE VARIANCE ARE COMPUTED FOR EACH TEST, WHILE ALL ITEMS ARE ANALYZED FOR DIFFICULTY LEVEL AND INTERNAL CONSISTENCY. THREE VALIDITY STUDIES REVEAL THAT THE BATTERY OF TESTS IS EFFECTIVE FOR PREDICTING TRAINING ACHIEVEMENT, BUT LESS CONCLUSIVE IN PROVIDING EVIDENCE FOR PREDICTING JOB PERFORMANCE. (SEVEN TABLES OF EXPERIMENTAL DATA, A TABLE OF PERCENTILE NORMS FOR COMPUTER PROGRAMER TRAINEES AND APPLICANTS AS WELL AS FOR EXPERIENCED PROGRAMERS AND SYSTEM ANALYSTS ARE INCLUDED.)
