All thematic pages for the LaNA 2023 Linking Study are now accessible on the ILSA Gateway. They provide comprehensive information on the assessment framework, instruments, implementation, international database, and key findings from this study, which was conducted for the first time as an off-cycle administration in six countries. LaNA measures foundational reading and mathematics skills at the end of primary school and is based on the frameworks of TIMSS and PIRLS. Designed for contexts where implementing TIMSS or PIRLS may be challenging, LaNA provides internationally comparable data while addressing the specific needs of participating education systems.

The results for TALIS Starting Strong 2024 are available on the ILSA Gateway. They include detailed findings from the survey of early childhood education and care (ECEC) staff and leaders across 17 countries and subnational entities. The findings provide insights into working practices, job satisfaction and stress, professional development, as well as challenges and the organization of the ECEC sector.

The additional thematic pages for TALIS 2024 are now accessible on the ILSA Gateway. They include detailed results from both TALIS core survey and TALIS Teacher Knowledge Survey (TKS). In TALIS 2024 core, more than 280,000 educators from 55 education systems shared insights into their initial education and professional development, teaching and assessment practices, use of artificial intelligence and many other aspects. The TALIS TKS results provide the first internationally comparable data on teachers' general pedagogical knowledge, based on responses from more than 20,000 lower secondary teachers across eight education systems.

Additional thematic pages for SEA-PLM 2024 are now accessible on the ILSA Gateway. They include further information on the study design, results, data, and related materials. SEA-PLM 2024 assesses students’ reading, writing, and mathematical literacy across the six participating Southeast Asian countries and collects contextual data from students, parents, teachers, schools, and the education system. The results provide insights into learning outcomes in the region and support evidence-based policy development.

The first pages of the International Early Learning and Child Well-being Study (IELS) 2025 have now been uploaded to the ILSA Gateway. The study examines foundational learning domains, including emergent literacy and numeracy, as well as executive function and social-emotional skills. These pages provide key information about the study, including its research questions, participants, and study design, and detailed insights into the study framework and organization. Additional information will be added as it becomes available.

All thematic pages for TIMSS 2023 are now accessible on the ILSA Gateway. In addition to the assessment framework, the pages now include detailed information on the study design, international results, data, and related materials. TIMSS 2023 measured the mathematics and science achievement of fourth and eighth grade students across the 64 participating countries. It also collected contextual data from students, parents, teachers, and schools to provide a comprehensive view of educational environments. The results highlight global trends in STEM education and offer policy-relevant insights.

Discover PISA–VET on the ILSA Gateway now! As the first ILSA to focus on vocational education and training (VET), the study provides essential insights into the skills of students in vocational pathways and the outcomes of initial VET programs across countries.
These new Gateway pages introduce the purpose and structure of the study, provide an overview of the assessment framework, and highlight key organizational features.

All thematic pages for PIAAC Cycle 2 are now accessible on the ILSA Gateway. These pages provide comprehensive information on the assessment framework, instruments, implementation, international database, and key findings. The study measures the literacy, numeracy, and adaptive problem-solving skills of adults aged 16 to 65, providing vital data on how these skills vary across and within countries. The results also shed light on the relationship between adult competencies and background variables such as education, employment, gender, age, and digital skills use.

The ILSA Gateway now features the first pages of PISA 2025. These pages present key information about the study, including its objectives, participating countries, design, assessment framework, and organizational structure. Additional information will be added as it becomes available.

All thematic pages for the International Computer and Information Literacy Study (ICILS) 2023 are now available on the Gateway. They offer detailed information on the study design, data, and results related to students’ computer and information literacy (CIL) and computational thinking (CT). ICILS 2023 explores variations in student CIL and CT within and across countries, reports relationships between the two constructs and students’ background characteristics, their use of ICT and other aspects. It also examines the broader contexts—such as national curriculum, policy, and resourcing contexts—in which digital skills are developed.
