This report gives the findings of a study designed to identify obstacles to career mobility among paraprofessionals in social service agencies and to make recommendations for opening channels for advancement. The experiences of a group of paraprofessionals hired in a special project in 1965 and 1966 by the National Committee on Employment of Youth (NCEY) provided data for the study. Obstacles were civil service requirements, professional standards, lack of supplementary training and education, and the insistence of a B.A. degree for eligibility to higher level jobs. Implementation of a national policy of guarantee of equal opportunity for advancement, (1) through measures designed to help paraprofessionals advance within the current framework of agency hiring policies and job structures, (2) through measures designed to help agencies change that framework, and (3) through measures designed to help fields of service re-evaluate the total framework of their services and use of manpower, is recommended. Specific ways of implementing the above recommendations are summarized. Appended are background information on the NCEY questionnaire, and a list of agencies employing and/or training NCEY graduates.
