In-Service training is among the important tools for updating the professional capabilities of librarians and skilled manpower working in research and educational institutions. Agriculture Scientific Information and Documentation Center (ASDIC), during the 2000-2004 periods, offered forty in-service courses. The present paper investigates the views of the instructors and learners participating in these courses. Findings indicate that 79% of instructors were satisfied with courses scheduling while 36% were dissatisfied with lighting, acoustics and air conditionings in the classes. 80% of the learners were satisfied with Courses notifications while 38% were dissatisfied with extracurricular activities. However there was a 85% satisfaction rate regarding the command and preparedness of instructors. The instructors proposed more specialized courses with shorter schedules, higher coordination with specialist groups within ASIDC in design and implementation of courses, as well as coordination with instructors for course scheduling. Learners proposed course follow-ups as well as instruction courses being offered in provinces that are equipped for it.
