A STUDY WAS MADE OF THE READABILITY LEVELS OF CURRICULUM MATERIALS USED IN THE BASIC AND THE VOCATIONAL EDUCATION PROGRAMS AT THE ATTERBURY JOB CORPS CENTER IN INDIANA. THE GUNNING FOG INDEX WAS USED TO MEASURE STYLE OF DIFFICULTY AS CREATED BY LENGTHY SENTENCES AND POLYSYLLABIC WORDS. THIS IS HIGHLY CORRELATED TO THE LEVEL OF SCHOOL GRADE ATTAINED BY THE READER. FIVE JOB SHEETS USED IN THE VOCATIONAL COURSES IN HEATING AND REFRIGERATION INSTALLATION AND RANDOM SAMPLINGS OF "SUCCESS IN LANGUAGE/A" AND "THE MONEY YOU SPEND" USED IN THE BASIC EDUCATION PROGRAM WERE ANALYZED. THE JOB SHEETS TESTED APPROXIMATELY AT THE FIFTH GRADE LEVEL. "SUCCESS IN LANGUAGE/A" TESTED AT THE SIXTH GRADE LEVEL, AND "THE MONEY YOU SPEND," AT FOURTH GRADE. CORPSMEN HAVING ATTAINED FIFTH OR SIXTH GRADE SCHOOL LEVELS OF READING SHOULD BE ABLE TO HANDLE THE MATERIAL. (STATISTICAL TABLES AND A BIBLIOGRAPHY ARE INCLUDED.) (RT)
