As we approach the 2030 Agenda deadline, the pivotal role of teachers in achieving Sustainable Development Goal (SDG) 4 aiming to ensure inclusive and equitable quality education and promote lifelong learning opportunities for all has become increasingly apparent. However, a global shortage of teachers is hindering access to education, with a projected deficit of 44 million teachers to achieve primary and secondary universal education by 2030. The result is overcrowded classrooms, diminished teaching quality, and limited learning opportunities, especially in underserved communities. The first UNESCO and Teacher Task Force Global Report on Teachers examines this urgent global challenge by drawing on new data and research. Entitled “Addressing teacher shortages and transforming the profession,” it provides practical insights and best practices to enhance teacher recruitment, retention, and professional development.
