ABSTRACT This study inspected the connection between educational expenditure and financial economic growth in Nigeria utilizing time series and secondary data from 1981 to 2018, sourced from the Central Bank of Nigeria (CBN), and the World Bank. Significant measurable apparatuses were utilized in investigating the connections between these factors. Stationarity attributes of the factors were tested utilizing the Augmented Dickey Fuller (ADF) procedure on Eviews. The relationships between educational expenditure, and economic growth were test through Ordinary Least Square analysis and Granger Causality test. The study had two hypothesis and its population was Nigeria. Several similar literatures were reviewed to aid in the analysis of our data. The discoveries show that educational expenditure has no causal connection with economic growth. The outcome additionally demonstrated that educational expenditure has a negative and inconsequential relationship with economic growth. The examination credited these discoveries to the way that educational expenditure during the time of study was twisted by superfluous factors, for example, strategy inefficiencies, poor financing, and funds misappropriation, and so forth. The investigation suggests that in accordance with global norms, the educational sector of Nigeria requires an institutional change as far as strategy detailing, execution and tracking finances. Likewise, need must be given to other genuine causal elements to economic growth.
