<![CDATA[This paper critically reviews the contributions of tertiary institutions to national development, with particular attention to key economic and social sectors including healthcare, agriculture, engineering and infrastructure, information and communication technology, education, industry and entrepreneurship. The paper adopts a critical review approach, drawing on policy documents, institutional reports, empirical studies and relevant literature on higher education, research and national development in Nigeria. The review establishes that Nigerian universities, polytechnics, colleges of education and other tertiary institutions contribute significantly to the production of skilled professionals, generation and dissemination of knowledge, development of agricultural technologies, training of health personnel, provision of engineering and digital skills, support for entrepreneurship, and provision of evidence for public policy. However, the developmental contribution of these institutions is constrained by inadequate and irregular funding, obsolete infrastructure and research facilities, weak university-industry linkages, skills mismatches, limited commercialisation of research findings, inadequate collaboration and weaknesses in the implementation of research outcomes. The paper argues that the developmental value of tertiary institutions should be assessed not only through enrolment, graduation and publication statistics but also through research utilisation, innovation, graduate employability, industry partnerships, entrepreneurship, policy influence and measurable community impact. The paper recommends increased and sustainable funding, improved research infrastructure, stronger university-industry-government collaboration, greater emphasis on applied and problem-oriented research, strengthened entrepreneurship and innovation ecosystems, curriculum reforms and improved mechanisms for translating research into products, policies, services and technologies. It concludes that tertiary institutions constitute critical components of Nigeria's human-capital and national innovation infrastructure and that strengthening their capacity is essential for sustainable and inclusive national development.]]>
