Ingrained in the Competency-Based Curriculum (CBC) is Community Service Learning (CSL), an instructional strategy where students are expected to actively address genuine societal challenges. This way, learning is made relevant and at the same time enhances students’ moral, social, civic, self-efficacy, political, economic, analytical, and career development skills. This novel learning strategy is critical in facilitating the realization of sustainable prosperity, including Kenya’s Vision 2030 development blueprint, which puts more emphasis on the connection between education and the labour market, fostering the acquisition of core competencies and life skills, and the necessity to fortify partnerships between the public and private sectors. This discourse explores the concept of CSL, its theoretical base, principles, and benefits, particularly in teacher education. Furthermore, the review delves into the implementation of CSL, including the possible sources of activities to be engaged in, projects to be carried out, and assessment.
