A survey of 104 Florida public library administrators resulted in a 70% response rate to a questionnaire investigating the value of a variety of types of activities associated with professional development. Presented as a poster session, this report indicates that the following professional and continuing education activities were considered the most beneficial in terms of investments of time, energy, and cost, to the survey respondents: (1) attending workshops, courses, or seminars; (2) reading professional library publications; (3) working with other librarians to learn or improve a skill; and (4) attending meetings of professional library associations. In response to an open-ended question asking for a description of one or two specific, most useful activities related to professional growth, 68% of the administrators indicated that participation in educational programs, such as workshops, seminars, or courses, was most productive from the standpoint of personal development. An appended table provides a quantitative description of survey results. (CGD)
