The Teaching and Learning International Survey (TALIS) is the first international survey that provides a voice to teachers and school principals, who complete questionnaires about issues such as the professional development they have received; their teaching beliefs and practices; the assessment of their work and the feedback and recognition they receive; and various other school leadership, management and workplace issues. TALIS relies on teachers' and school leaders' expertise as professionals to describe their work situation as accurately as possible, as well as their experiences in and feelings about their schools and working conditions. It is not an assessment, but a self-reported survey.
TALIS is the outcome of a collaboration between its participating entities (countries and territories), the OECD, an international consortium, Education International (representing teacher unions) and the European Commission. It also benefits from the input of other social partners, such as UNESCO. TALIS is a periodic survey: after its first three successful cycles in 2008, 2013 and 2018, the fourth cycle of the TALIS will take place in 2024.
TALIS aims to contribute to the debate about teaching as a profession. In the previous cycle in 2018, nine main themes were selected for inclusion in the TALIS survey: teachers’ instructional practices, school leadership, teachers’ professional practices, teacher education and initial preparation, teacher feedback and development, school climate, job satisfaction, teacher human resource issues and stakeholder relations, and teacher self-efficacy. Two cross-cutting themes were added to this list: innovation, and equity and diversity. More information on the conceptualisation of the eleven themes can be found in the Teaching and Learning International Survey (TALIS) 2018 Conceptual Framework.
Volume I of the TALIS 2018 results, Teachers and School Leaders as Lifelong Learners, are related to the knowledge and skills dimension of teachers’ and school leaders’ work. It looks at how teachers apply their knowledge and skills in the classroom in the form of teaching practices, the demographic makeup of classrooms shaped by student diversity and the demographic and experience profiles of teachers and school principals. It also looks at the initial training provided to teachers and school leaders, as well as the activities they undertake for continuous professional development. Volume II of the TALIS 2018 results, Teachers and School Leaders as Valued Professionals, focused on prestige and job satisfaction, career opportunities, collaborative culture, and professional responsibility and autonomy.
Three further volumes, on the TALIS-PISA link module, the primary and upper secondary modules (ISCED 1-3 modules), and on equity, were produced. For a full list of published materials, check the publications page.
Consult the list of participants for an overview of participation over the previous and current cycles.
The first cycle of TALIS was conducted in 2008 in 24 countries. The second cycle, TALIS 2013 – included 38 participants (34 participants in 2013 and 4 additional participants in 2014 and 2015). The previous cycle of the study, TALIS 2018, expanded to include additional countries, bringing the total number of participants to 48 countries and territories. TALIS 2018 was answered by over 260 000 teachers and 15 000 school leaders from lower secondary, primary and upper secondary education levels.
In 2024, the main survey (ISCED level 2) will be conducted in 33 OECD countries and territories – Alberta (Canada), Australia, Austria, Belgium (the Flemish and French communities), Brazil, Chile, Colombia, Costa Rica, the Czech Republic, Denmark, Estonia, Finland, France, Hungary, Iceland, Israel, Italy, Japan, Korea, Latvia, Lithuania, Mexico, the Netherlands, New Zealand, Norway, Poland, Portugal, the Slovak Republic, Slovenia, Spain, Sweden, Türkiye and the United States. Non-OECD member countries who are participating – Albania, Azerbaijan, Bahrain, Brazil, Bulgaria, Croatia, Cyprus,,, Kazakhstan, Malta, Montenegro, Morocco, North Macedonia, Romania, Saudi Arabia, Shanghai (China), Serbia, Singapore, South Africa, the United Arab Emirates, Uzbekistan and Viet Nam.
Additionally, 14 countries and territories will survey teachers and school leaders in their primary (ISCED level 1) schools, 8 in their upper secondary (ISCED level 3) schools, 16 will participate in the Starting Strong module (ISCED 0, with 7 of them participating in the Under 3 option) and 8 will conduct the Teacher Knowledge Survey optional module.

Apart from participating entities and the OECD, TALIS data is available for download to anyone who is interested in exploring the data. Usually, TALIS data is used by interested researchers and data analysts working in the disciplines of social science and education. In addition to the TALIS international and national datasets, researchers and data analysts can use TALIS online tables available on OECD.Stat, the TALIS 2018 Technical Report, the OECD Education GPS and Compare your country as an aid to pursuing further research using the TALIS data.
Compared to previous cycles, TALIS 2024 has expanded in terms of scale, depth and scope.
The aim of TALIS is to produce rich and reliable information on the whole population of teachers and principals in a given country or territory. Therefore, it collects a wealth of information from a representative group of teachers and principals, in a timely fashion. TALIS results are based exclusively on self-reports from teachers and school leaders and, therefore, represent their opinions, perceptions, beliefs and accounts of their activities. No data imputation from administrative data or other studies is conducted. Giving a voice to teachers provides insight into how they perceive the learning environments in which they work and how policies that are put in place are carried out in practice. But, as with any self-reported data, this information is subjective and may, therefore, differ from data collected through other means (e.g. administrative data or video observations). The same is true of school leaders’ reports about school characteristics and practices, which may differ from descriptions provided by administrative data at a national or local government level.
Two questionnaires are developed in TALIS: a teacher and a principal questionnaire. The goals of and the themes included in the questionnaires are identified by the TALIS Governing Board, which is comprised of participating countries and territories and the European Commission. Input is also received from Education International.
The development of the questionnaires is undertaken by a Questionnaire Expert Group (QEG), managed by the TALIS consortium. The QEG develops a conceptual framework that guides the questionnaire development. Upon participants’ approval of the conceptual framework, the QEG translates the goals and priorities into survey questions.
Questionnaire development has three major phases: a pilot, a field trial and a main survey. The pilot study is conducted in a large number of participating countries and territories and consists of collecting feedback on the draft questionnaires from teachers and principals convened in focus groups. The main goal of the field trial is to collect quantitative information about the statistical and psychometric properties of the questions in all participating countries and territories, for example, to check whether questions measure the same concepts across all participants and are properly translated. After each phase, the draft questionnaires are revised and reviewed by the QEG and approved by the participating countries and territories. Upon approval by the TALIS Governing Board, their final versions are used in the main survey. Through all of this process, relevant social partners are consulted and provide feedback on the development of the conceptual framework and the questionnaires.
The themes covered in the TALIS questionnaires are those identified as priorities by participating countries and territories through a priority rating exercise (for TALIS 2018, this was conducted in 2015), as well as those identified by the ministers of education in the International Summit on the Teaching Profession (ISTP). Beyond these common priority themes, a participant has the possibility of adding its own questions to the survey. To ensure the international comparability of the questionnaire, country or territory extensions and adaptations are kept to a strict minimum and require review and pre-approval by the Consortium. No question can be dropped, which is why some questions may seem less relevant in a specific country's or territory's context.
The international target population for TALIS consists of schools providing lower secondary education, as well as their principals and teachers. TALIS countries and territories can also opt to survey primary and upper secondary teachers and principals. To enable comparability of education systems, the international target population of TALIS excludes some special schools, such as schools exclusively for adult education or for students with special needs. From the participant lists of eligible schools, TALIS randomly samples 200 schools per participant, and then selects 1 school leader and randomly samples 20 teachers in each sampled school. OECD recommends that participation in this survey is voluntary and any individual may withdraw from the survey at any time.
The selected teachers and school principals are asked to answer a teacher or a principal questionnaire. The questionnaires are administered on line or on paper and their completion requires between 45 and 60 minutes.
All information that is collected in this study is treated anonymously and confidentially. While results are made available by participant and, for example, by the type of school within a country or territory, neither the teachers, the school principals, the schools nor any school personnel can be identified in any report of the results of the study. In addition, no staff member within the school has access to the answers provided by a colleague.
The answer is a clear "No". Such a use of the data would require being able to identify schools, teachers and principals in the databases, which is not possible. A school, a teacher, or a principal is always treated as an anonymous data point among hundreds of thousands other data points. TALIS cannot and does not intend to provide the results for any individual school, teacher or principal.
TALIS is focused on the following policy priorities for education systems – attaching high-achieving candidates in the profession; providing quality initial and continuous training to newly recruited teachers and in-service teachers; support teachers in the continuous development of their careers and spread good practices; foster job satisfaction and status of the profession, with a view to retaining quality teachers and school leaders.

TALIS has finished recruiting countries and territories interested in participating in its current data collection cycle in 2024 (TALIS 2024). Applications to participate in the next cycle of TALIS (TALIS 2030) will be considered upon receipt of an official letter informing the OECD of a country/territory’s desire to participate in TALIS, including confirmation of its intention to contribute to the international costs. For the next cycle, interested countries or territories should get in touch with the TALIS Secretariat (contact firstname.lastname@example.org) in 2025-26 to receive information on the participation process.
The fourth cycle of the study, TALIS 2024, entails a working period commitment of six years (2021-26), as preparations start well before survey administration and reporting of results takes place about a year later. Countries and territories interested in joining TALIS are expected to fulfil the following requirements:
- Contribute to the international costs of the survey.
- Cover national implementation costs.
- Nominate a representative for the TALIS Governing Board (TGB): This board is represented by all participating countries and territories at senior policy levels and is responsible for specifying the policy priorities and standards for the development of indicators, establishment of survey instruments, and the reporting of results. The TGB meets about twice a year – usually February/March and October/November. Participation in the TGB for non-OECD countries and territories is optional.
- Appoint a national project manager (NPM) to carry out the surveys in the national context: The national project managers work with the OECD contractor on all issues related to the implementation of TALIS in their country or territory. NPMs play a vital role in ensuring that TALIS is a high-quality project with results that can be verified and evaluated following OECD quality standards. They can also play an important role in the development and review of TALIS reports and publications, in consultation with their respective TGB member.
Other tasks for participating countries and territories:
- Take responsibility for drawing a representative sample of schools and teachers in compliance with the internationally agreed target population definitions and sampling procedures. In TALIS 2018, the field trial included a sample of approximately 30 schools and 600 teachers and the main study a sample of approximately 200 schools and 4 000 teachers.
- Have the authority and resources to recruit schools to participate and to administer the survey following a computer-based delivery system. Paper-based implementation might be an option at the request of participants and based on their capacity to manage printed materials.
- Oversee and cover the costs of translation and adaptation of the questionnaire and deal with related issues.
- Have the capacity for data collection, processing, quality assurance and reporting progress to the consortium.
It is too early to provide costs for the next full cycle. To note, in addition to participation in the main survey (i.e. lower secondary schools), there are additional costs for for participation in any optional modules.
Participants from the EU/EEA should be aware of the possibility of financial support by the European Commission for the cost of participation in the main survey.
In addition to the above international costs, the costs for the national implementation of the programme are borne entirely by participants. Participants are also required to cover the costs for international travel to attend the TALIS Governing Board meetings (optional for partner countries and territories) and the national project manager meetings.
