FACTORS RELATED TO PARTICIPATION IN CONTINUING EDUCATION WERE EXPLORED BY A QUESTIONNAIRE ANSWERED BY 435 WORKING ENGINEERS, ALL GRADUATES OF THE GEORGIA INSTITUTE OF TECHNOLOGY, CLASSES 1948-63. INDEPENDENT VARIABLES WERE EDUCATIONAL BACKGROUND, JOB, GEOGRAPHY, AND PERSONAL CHARACTERISTICS. DEPENDENT VARIABLES WERE THE TYPES OF EDUCATIONAL ACTIVITIES THE ENGINEER MIGHT ATTEMPT--COURSE WORK, PROFESSIONAL ACTIVITIES, READING AND SELF-DIRECTED LEARNING, AND CORRESPONDENCE STUDY. JOB-RELATED FACTORS SEEMED TO DETERMINE PARTICIPATION TO THE GREATEST EXTENT, ALTHOUGH CERTAIN AGE-RELATED FACTORS, ANNUAL SALARY, AND MARITAL STATUS WERE ALSO FOUND TO BE OPERATIVE. YOUNGER MEN IN CITIES, WHO HAD BEEN AT THE TOP OF THEIR CLASSES, FAVORED COURSE WORK, WHILE OLDER MEN WERE OFTEN PARTICIPANTS IN THE ACTIVITIES OF SEVERAL PROFESSIONAL SOCIETIES. PARTICIPANTS IN READING AND SELF-DIRECTED LEARNING COULD NOT BE NEATLY DELINEATED BY THE FACTORS STUDIED. THE STUDY INCLUDED A LITERATURE REVIEW, STATISTICAL ANALYSES OF THE RELATIONSHIPS AMONG FACTORS, AND RECOMMENDATIONS FOR FURTHER RESEARCH.
