Questionnaires concerning major problems facing youth in the transition from school to work were mailed to all counselors at the 167 Youth Opportunity Centers (YOC) of the U.S. Employment Service. Data were obtained from usable returns by 763 (59 percent) counselors. The problems were categorized into nine major categories (job preparation, personality variables, vocational behavior, school programs, discriminatory factors, family background, community factors, factors inherent in job, and military obligation), and 50 sub-categories. Problems enumerated by YOC counselors and by a purposive sample of vocational educators (Garbin, et al., 1967) have a correlation of .61 (Spearman) which increases the probability that these are real problems facing youth. Counselors recommended that schools provide better occupational information, more vocational guidance, and additional courses teaching basic prevocational skills. Other reports in this series are available as ED 016 811, ED 021 070, and ED 032 430. (CH)
