This study examines the role of public–private partnerships (PPPs) in enhancing Technical and Vocational Education and Training (TVET) in Nigeria, motivated by persistent youth unemployment and skills mismatches. Using Human Capital Theory, Public Choice Theory, Institutions Theory, and Stakeholder Theory, the study analyzes data from major Nigerian initiatives, including ITF–NECA Technical Skills Development Project, Dangote Academy, NCDMB’s Oil & Gas Content Program, BOI–ITF Graduate Entrepreneurship Fund, Lagos State Employment Trust Fund, Nigerian Breweries Technical Schools, and UNDP-supported vocational projects. Empirical review of reports, program evaluations, and field data reveals that PPPs improve employability, sectoral relevance, and capacity building, particularly where employers are deeply engaged. However, challenges remain: sectoral concentration, regional inequities, fragile financing, and weak monitoring. Policy analysis shows that sustainable levy-based financing, structured employer engagement, quality assurance, and deliberate inclusion of women, rural youth, and SMEs are key to scaling impact. Recommendations emphasize expanding outcome-based financing via the Bank of Industry, modernizing levies, strengthening sector skills councils, and scaling hub-and-spoke training models to underserved regions. The study concludes that while Nigerian PPP-driven TVET initiatives have demonstrated measurable impact, systemic reforms are necessary to ensure equity, scalability, and resilience in skills development.
