The purpose of this study is to evaluate the effects of innovativeness and internal locus of control on agro-entrepreneurial intention as well as the mediating role of innovativeness on the relationship between internal locus of control and agro-entrepreneurial intention among secondary school students in Nigerian. Using structural equation model on 200 secondary school students in Sokoto state, we found that the agro-entrepreneurial aspirations of secondary school students are significantly related to one’s innovativeness, while internal locus of control has no significant effect. Also, internal locus of control significantly influences one’s innovativeness. Finally, innovativeness has a full mediating effect on the relationship between internal locus of control and agro-entrepreneurial intention. Thus, the Nigerian government and other government entities are reminded by this study of the importance of continuing to develop training programs and activities to support psychological traits in young agro-entrepreneurs.
