The OECD teachers' occupational well-being framework contributes to understanding and measuring the occupational well-being of teachers between and within systems. It provides a pathway to explore the association between the quality of working environments and teachers' levels of occupational well-being. It also covers the association of teachers' occupational well-being with the quality of learning environments (measured by classroom quality processes and association with students' well-being) and teachers' stress levels and motivation to continue teaching.
