The OECD Teaching and Learning International Survey (TALIS) is the largest international survey of teachers and principals. It was first introduced in 2008, then administered cyclically in 2013, 2018 and 2024. By collecting internationally comparable information about teachers, teaching and principals, TALIS ensures that the voices of teachers and principals are represented in education policy making.
What is TALIS?
Copy link to What is TALIS?Introduction
Copy link to IntroductionWhat data does TALIS collect?
Copy link to What data does TALIS collect?TALIS captures information about a variety of aspects related to teachers and teaching. For example, TALIS collects data about teacher demographics (e.g. age, gender) and their schools’ characteristics (e.g. size, location). Teachers also provide information about their working hours, professional learning, contract modalities, professional and teaching practices, school climate, well-being, job satisfaction and career intentions.
Each cycle, TALIS introduces new survey questions to capture contemporarily relevant information. In 2024, TALIS asked teachers about how they adapt to increasingly diverse student populations, their use of technology and artificial intelligence, how they respond to students’ social and emotional needs, and their practices and attitudes related to environmental sustainability.
More information about the data collected by TALIS can be found in the TALIS 2024 Conceptual Framework (OECD, 2025[1]).
How is TALIS implemented?
Copy link to How is TALIS implemented?The TALIS Governing Board (TGB) leads TALIS. It is composed of a representative from each country and territory that participates in the survey. The TGB oversees the OECD Secretariat, which in turn manages a consortium of international actors that together develop and implement TALIS.
A diverse group of education experts, guided by the TGB, drafts the questions that appear in TALIS. Each question is translated into the national languages of every participating country and territory. The questions are tested twice to verify their translations and their functioning.
Each education system chooses to administer TALIS in up to three levels of education: primary (International Standard Classification of Education or ISCED level 1), lower secondary (ISCED level 2) and upper secondary (ISCED level 3). Within each level in each country or territory, a representative sample of roughly 4 000 teachers from 200 schools complete the survey along with their school principals.

1. Cyprus did not participate directly in TALIS 2024: its data collection and processing were managed exclusively by the international research consortium. Its data are reported in the result tables listed in Annex C.

1. Four countries and territories, including Georgia, New Zealand, the Russian Federation and Shanghai (China), collected data in 2014.
Other survey modules within the TALIS programme
Copy link to Other survey modules within the TALIS programmeThe TALIS Teacher Knowledge Survey (TKS) module, which is closely connected to the Core Survey at ISCED level 2 and designed to study teachers’ general pedagogical knowledge, was introduced for the first time in the 2024 TALIS cycle.
The Starting Strong Teaching and Learning International Survey 2024 is an important international, large-scale survey in early childhood education and care (ECEC), focusing on early childhood staff and setting leaders. It was first implemented in 2018 and continues to cover staff and leaders at ISCED level 02 (pre-primary settings) as well as in settings for children under the age of three.
