This study investigated how the strategic management of quality assurance mechanisms influences academic standards in public tertiary institutions in Imo State, Nigeria. A context where reactive compliance rituals have left graduate quality uneven despite robust national policy frameworks. Guided by a pragmatist philosophy, an explanatory-sequential mixed-methods design was employed. First, quantitative data were collected from 374 participants (300 academic staff, 50 administrators, and 24 final-year students) stratified across five public institutions, three universities, a college of education and a polytechnic. Survey responses were analyzed using SPSS v29, revealing that strategic quality-assurance inputs explained 54 % of the variance in perceived academic standards; integration of QA objectives into institutional strategic plans emerged as the strongest predictor (β = .42, p < .001). A qualitative phase followed, involving interviews, focus groups, and document audits (2020–2025) thematically coded in NVivo v14. Qualitative findings showed that institutions with updated QA plans, visible executive leadership, and dedicated budget lines (≥ 2%) scored markedly higher on a composite QA management index, while those lacking these attributes stagnated. Funding deficits, academic inertia, and weak data systems were identified as key moderators. The study concludes that quality assurance serves as a genuine lever for academic excellence only when proactively planned, adequately resourced, and leadership-mediated. Targeted fiscal incentives, differentiated accreditation cycles, and stakeholder governance reforms are recommended for Imo State and similar contexts.
