[en] In order to assess the impact and the quality of the International Atomic Energy Agency (IAEA) fellowship programme, the Department of Technical Cooperation conducted a survey among former fellows from the years 2001 and 2002. These fellows have all completed the fellowship training, and have had time to judge in what way their training is useful to their work in their home country. As a result of this survey, further surveys could be conducted to serve as a continuous systematic assessment of the fellowship and other programmes. Former fellows from the years 2001 and 2002 were asked to fill out a questionnaire containing questions regarding the following: Where are the former fellows now and what are they doing? How did the fellows rate the quality of the fellowship programme? How did the fellows rate the impact of the training they received through the fellowship programme, the impact on their home institution, and the impact on the TC project and their home country? The survey period was 11 February - 4 March 2005. Reaching a sufficient number of former fellows from the years 2001 and 2002 posed some difficulties. The National Liaison Officers contributed greatly in finding the former fellows' current contact information. Out of the 2067 fellows who were in the field in the years 2001 and 2002, 613 participated in the survey (meaning, 30% of all fellows from those years and 50% of those reached by email or fax). The results of the survey given below represent only the survey participants' opinions, not those of all former fellows from the years 2001 and 2002. To ensure that the results are representative of all fellows, a follow-up study of seven countries is currently being done. The IAEA fellowship programme contributes successfully to knowledge and technology transfer to fellows' home institutions, their home countries and the TC projects they are involved in, as evidenced by the following survey results: 94% of the fellows who participated in the survey returned to their home institution in their home country and apply the skills and knowledge acquired during their trainin; 88% think the ideas and knowledge acquired during the fellowship are useful for their work; 96% of participating fellows shared their knowledge with colleagues and students in their home institutions through presentations, workshops, on-the-job training, individual consultations and teaching; 70% developed useful contacts during the fellowship, and 74% are still in touch with their host institution, which contributes to ongoing knowledge transfer from the host to the home institution; The quality of the fellowship programme itself is judged very highly, as evidenced by the following results: Both the host institution and the training programme are considered suitable or very suitable by 85% of the participating fellows; 81% feel that the guidance they received was good or very good; 82% of the fellows who participated found the quality and adequacy of the facilities made available to them good or very good. Participants also included suggestions to improve the IAEA fellowship programme and ideas for enhancing its impact. Among the latter, a systematic follow-up is mentioned frequently; suggestions include the establishment of mechanisms for continuous contact between the home and the host institution and platforms for regional and interregional information exchange
