Systemic Determinants of Teacher Quality in Nigeria: A Multi-Level Analysis Across Geopolitical Zones

This study investigates the systemic determinants of teacher quality across Nigeria's six geopolitical zones, employing a multi-level analytical framework to disentangle individual, school, and policy-level factors that explain variation in teaching effectiveness. Teacher quality is the single most powerful within-school determinant of student learning, yet the structural and systemic conditions that produce and sustain quality teaching in Nigeria's heterogeneous school system remain theoretically underdeveloped. The study employs a multi-level mixed-methods design, drawing data from 1,200 teachers and 180 school administrators across 60 purposively sampled secondary schools in six states: Lagos, Enugu, Rivers, Kano, Plateau, and Borno. Classroom observations, teacher assessments, and administrative questionnaires constitute the quantitative data sources, supplemented by elite policy interviews at federal and state ministry levels. Three-level hierarchical linear modelling, structural equation modelling, and critical policy discourse analysis were applied. The study integrates Darling-Hammond's Teacher Quality Framework, Bernstein's Pedagogic Device Theory, and the Capability Approach of Sen and Nussbaum. Findings are expected to generate a tested multi-level model of Nigerian teacher quality determinants, identifying pre-service preparation quality, professional autonomy, and working conditions as mediating institutional variables. Recommendations provide system-level policy evidence for the Federal Ministry of Education, state governments, and development partners on targeted investment in teacher quality systems.
