How can countries prepare teachers to face the diverse challenges in today’s schools? The OECD Teaching and Learning International Survey (TALIS) helps answer this question by asking teachers and school leaders about their working conditions and the learning environments at their schools. TALIS aims to provide valid, timely and comparable information to help countries review and define policies for developing a high-quality teaching profession. It is an opportunity for teachers and school leaders to provide input into educational policy analysis and development in key areas. Themes explored include professional development, school leadership, teaching practices, school climate, appraisal and feedback, job satisfaction and teacher profiles.
