Purpose The purpose of this study is threefold: first, to determine whether civic education has a positive impact on voting intentions among the electorate; second, to establish whether attitudes towards voting behaviour (ATVB) mediate the relationship between civic education and voting intentions; and third, to determine whether educational level moderates the relationship between civic education and voting intentions. Design/methodology/approach This study adopted a survey research design and a quantitative approach. Data were collected from a sample of 1,450 registered voters from the six geopolitical zones of Nigeria. A regression-based approach was adopted to test the study hypotheses using Hayes-PROCESS Macro 3.5. Findings The results indicate that civic education is positively associated with voting intentions. Further analysis reveals that ATVB significantly mediates the association between civic education and voting intentions. Additionally, educational level positively moderates the relationship between civic education and voting intentions. Practical implications The findings offer implications for governments and democratic institutions. Originality/value To the best of the authors’ knowledge, this is the first study to provide empirical evidence of the mediating effect of ATVB and the moderating effect of educational level on the relationship between civic education and voting intentions. This study provides useful insights into the factors that influence voting intentions.
