Confirmatory factor analysis, Extension services, Ethics, Professionalisation


The need for agricultural extension services in Nigeria to attain a higher ethical and professional status of registering and certifying its service providers like other disciplines for effective service delivery has led this study to examine the factors influencing extension professionalisation in Nigeria. 356 extension agents from both public and private extension organisations were selected through a two-stage sampling procedure. A structured questionnaire was used to elicit information on the knowledge, attitude and perceptions on the effects of the components of professionalisation (i.e. accreditation, registration, and certification) on service delivery. The Cronbach alpha reliability values for the constructs used in the different sections of the instrument were knowledge (0.78), attitude (0.94), accreditation (0.92), registration (0.89) and certification (0.96). Data was analysed using IBM AMOS version 24 to conduct a confirmatory factor analysis to determine the interrelationships that exist between the extension agent’s knowledge, attitude, and the components of professionalisation. The findings revealed a significant and strong positive correlation between the constructs of the extension agent’s knowledge, attitude and the professionalisation components of accreditation, registration, and certification. These findings have implications for educating and training extension agents on professionalisation and its components to ensure its institutionalisation in the agricultural extension sector for the provision of a more ethical, competent, accountable, and efficient rural and advisory service delivery.
