This article reports on a survey of librarians on their view of the role of the Iranian Library and Information Science Association in informal education of librarians. The survey uses a descriptive-analytical approach with categorized sampling of two groups of members in Tehran and Khorasan. The results show that the association is successful in holding informal training programs for librarians. The T test indicates no significant difference between librarians in Tehran and in Khorasan except in two factors. The difference is shown in positive effect on job evaluation, and suitability of scheduled dates, date of monthly seminars, and level of education. The F test shows no significant difference between member categories except in three factors. The difference is in the suitability of subjects, the number of librarians attending, and the factor of history of the association.
