Technology for Teaching (T4T) is the World Bank's program to assist countries implement effective, scalable teacher professional development (TPD) programs that use low- and high-technology solutions to train and support teachers/Pedagogical Leaders (PLs). T4T provides practical tools to policymakers and practitioners for designing and implementing operationally feasible tech-based TPD in their contexts, thus contributing to build inclusive and resilient education systems. This Note presents common barriers that teachers/PLs face at each TPD stage and offers operationally feasible, tech-based mitigation strategies. These will enhance access to and engagement with TPD, will improve application of skills and knowledge in the classroom, and can be implemented in low-resource contexts. Drawing on emerging research and successful on-the-ground programs that support teachers/PLs from across the globe, this Note can be used by policymakers and practitioners to consider a range of options to address implementation barriers and scale up TPD programs using technology.
