This study investigates the effect of strategic mapping and performance of the Independent National Election Commission (INEC). The specific objectives were to ascertain the effect of electoral education on participation of electorate during election in Nigeria as well as to examine how modes of releasing election results minimizes the post-election agitations. The study adopted a survey research design. The sample size of 405 staff of INEC and officers of the two major political parties were selected across six geopolitical zones at the rate of 3 states per zone, including FCT Abuja. The hypotheses were tested using linear regression analysis at 5% level of significance. The findings indicated that: Electoral education by INEC significantly promotes electorates’ participation during election in Nigeria (β =0.612; t-value= 10.377; pvalue= 0.000), and the mode of releasing election results significantly minimized the post-election agitations in Nigeria (β =0.718; t-value= 12.821; p-value= 0.000). The study concluded that strategic mapping by INEC has enhanced their performance as electoral umpire in Nigeria. The study recommended that the management team in INEC should intensify in various aspects of electoral process through strategic mapping, to further achieve better performance as electoral umpire.
