"The OECD Teacher Knowledge Survey (TKS) is the first large-scale study of teachers’ general pedagogical knowledge with internationally comparable data from representative samples of teachers. In 2024, over 20 000 teachers from lower secondary schools in eight countries participated in this new optional module of the Teaching and Learning International Survey (TALIS). Teachers completed an assessment of their general pedagogical knowledge and reported on their professional experiences, practices, and perceptions. The results provide policymakers and researchers with valuable insights into the importance of pedagogical knowledge, where to find it and how to support its development."
