In examining characteristics, attitudes, and opinions of the students in the College of Agriculture, University of Khartoum, in the Sudan, this study focused on eight independent variables: years in the College of Agriculture, location of permanent home, size of home town, length of hostel living experience, father's occupation, number of living brothers and sisters, previous work experience, and standing in Sudan School Certificate. A questionnaire was developed and administered to students in four undergraduate classes. Most of the students believed that agricultural extension was needed for the improvement of Sudanese agriculture. In the light of 13 qualities and characteristics recommended for effective extension work, and using a cumulative measuring scale, the students were separated into three categories of potential suitability to extension work. Thirty percent fell in the highly suitable category. The offering of an option for agricultural specialization in the senior year was disadvantageous to agricultural extension. Students' potential suitability to extension work was related to the father's occupation and the length of time the person lived in hostels. Six independent variables failed to explain the reasons for the differential levels of potential suitability to extension work demonstrated by the students. (Author/NL)
