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 eservices 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 eservices at the university.
