This document discusses competency-based education and training (CBET) and its potential implications for sustainable national security and development in Nigeria. It defines CBET as an approach that focuses on what learners can do upon completion rather than the learning process, with competencies based on industry standards. The key characteristics of CBET include selecting carefully defined competencies, integrating skills practice with supporting theory, self-paced learning, and assessing mastery of individual competencies. Implementing CBET in technical and vocational education in Nigeria could help address the lack of employable skills among graduates and in turn reduce unemployment, increasing national security and development.
