The establishment of electronic services (e-services) has been an important policy goal in many universities worldwide. This notwithstanding, staff access to e-services and its reliability still remains an issue of concern that can hinder use of these services. The use of e-services in operational processes of teaching and administration can support staff to improve their work performance and promote competitive advantage for the university. However, many factors determine the use of e-services for staff in their day-to-day operations. This study is focused on towards academic and non-academic staff of the University of Nairobi, College of Agriculture and Veterinary Sciences (CAVS). Specifically, the aim was to identify the factors that determine e- services use. An empirical study was carried out whereby data was collected through a survey questionnaire administered face to face with a total of 100 academic and non-academic staff users of e-services. The results were obtained from econometric modelling that is Logit regression. The evidence from staff in CAVS gave a set of factors that included staff characteristics and organizational constraining factors of e-services. The perception they had about e-services led them to the kind of choice they made and the intensity of e-service use. Other factors that emerged were seen as some amenities that should be enhanced to allow staff to access and sustainably use e- services at the university.
