This research work is An Assessment of the Effect of Universal Basic Education on the Educational Development of Bauchi and Ganjuwa Local Government Areas of Bauchi State this becomes necessary because Education is the solid bedrock upon which every form of development: social, political, religious and economic is anchored. This further explains why it is perceived as a veritable tool and as well catalyst for national development. Universal Basic Education which is supposed to be free, compulsory andaccessible has remained unachievable and still faces the challenges of low students enrolment rates, high prevalence of school dropout and an acute shortage in the provision of infrastructural facilities necessarily needed to facilitate learning and teaching processes within the school environment eighteen years after its formal inauguration.Therefore, thestudy is concerned about establishing relationship between increase in enrolment, retention and completion rates and the provision of infrastructural facilities with educational development in order to know whether the sector is developing over time.Three Hypotheses were postulated to that effect. Survey method was adopted for data collection. The total number of sampled respondents stood at 394 drawn from the selected local government areas. Multiple regression statistical analysis model was employed to determine the significant effect of the variables on educational development of the areas. The finding of the research revealed that, pupil's enrolment in school affect educational development significantly though not sufficient enough to cause it but implies that any increase in pupil's enrolment will have multiplier effect on educational development. It also revealed that, pupil/students retention and completion in schools had the most significant share of the effect on educational development. Infrastructural facilities were non-available, dilapidated or grossly inadequate for use. The study therefore recommended that school feeding programme should not be discontinued in order to boost enrolment and retention and UBE should ensure adequate provision of infrastructural facilities.
