This paper advances scholarship by critically examining the opportunities and challenges of digital transformation in Nigerian secondary education, with a focus on how emerging technologies can address systemic inequities and improve learning outcomes. The study provides new insights into the adoption of individualised instructional approaches and efficient assessment practices, while also identifying persistent barriers, including inadequate infrastructure, limited digital literacy, and data privacy concerns. Grounded in the Technology Acceptance Model (TAM) and the Unified Theory of Acceptance and Use of Technology (UTAUT), this study contributes to the literature by identifying critical determinants of technology adoption perceived usefulness, ease of use, social influence, and necessary infrastructure. It advances implementation strategies by emphasising stakeholder involvement, capacity development, and equity in system design and deployment. Through this analysis, the paper offers actionable suggestions for policymakers, educators, and stakeholders to support the inclusive, equitable, and sustainable adoption of technology in Nigerian secondary schools, thereby advancing research and practice in the field.
