This study examines the effect of internally generated revenue (IGR) on basic education service
delivery in Kaduna State, Nigeria. Despite significant fiscal reforms and IGR growth exceeding
70% between 2015 and 2020, the state continues to experience educational deficits including
inadequate classroom infrastructure, teacher shortages, and poor learning outcomes. The
study objectives were to: (i) examine the effect of IGR on education facility adequacy and
teaching resources; (ii) assess the relationship between IGR performance and education
service quality; and (iii) determine the extent to which IGR influences overall education service
delivery in Kaduna State LGAs. A quantitative survey design was adopted, with structured
questionnaires administered to 344 respondents across nine purposively selected Local
Government Areas (LGAs) representing urban, semi-urban, and rural contexts. A composite
index measuring education facility adequacy, teaching materials availability, teacher quality,
student outcomes, and service accessibility was regressed against internally generated revenue
(IGR) performance indicators using Linear Regression Analysis. The analysis revealed that
IGR significantly and positively affects basic education service delivery, explaining 33.7% of
the variance in education outcomes (R² = 0.337, p < 0.001), with a standardized coefficient of â
= 0.580. For every one-unit increase in IGR performance, education service delivery improves
by 0.652 units. Post-estimation diagnostics confirmed model validity (Variance Inflation
Factor = 1.000), satisfying key regression assumptions. The study concludes that internally
generated revenue is a critical determinant of education service quality at the grassroots level,
with important implications for fiscal decentralization policy and education sector financing in
Nigeria. Recommendations include strengthening revenue administration systems,
establishing dedicated education financing mechanisms, and enhancing accountability
structures to maximize IGR impact on education outcomes.
