Teacher Training and Professional Development: Assessing the Quality of Teacher Training Programs and Ongoing Professional Development Initiatives in Improving Teaching Practices in Kenya

Despite significant investments in pre-service and in-service teacher education, disparities in instructional quality and learning achievements persist across the country, particularly between urban and rural schools. The purpose of the study was to assess how structured teacher training, continuous professional development, and school-based learning communities influence instructional competence and classroom performance. The study was guided by Mezirow’s Transformative Learning Theory, which posits that critical reflection on prior assumptions facilitates meaningful changes in beliefs, perspectives, and behaviours. A secondary data methodology was employed, analysing peer-reviewed journal articles, government reports, policy documents, and previous empirical studies published between 2020 and 2024. Data were synthesised using content analysis to identify trends, gaps, and outcomes related to teacher development initiatives. The findings indicated that pre-service training equips teachers with foundational pedagogical knowledge, while continuous professional development and mentoring programs significantly improve learner-centred teaching, classroom management, and assessment strategies. School-based professional learning communities enhanced collaboration, reflective practice, and adoption of innovative instructional methods. However, challenges such as limited resources, unequal access, large class sizes, and inadequate monitoring constrained the effectiveness of these programs. The study concluded that sustained, contextually relevant, and collaborative teacher development initiatives are crucial for improving teaching quality. Based on the findings, the study recommended expanding equitable access to training, integrating mentoring and technology, providing adequate resources, and establishing systematic follow-up and evaluation mechanisms.
