data.pisa4u.gr is an online platform for processing, analyzing, and visualizing data from the Programme for International Student Assessment (PISA) of the Organization for Economic Cooperation and Development (OECD). Its development is part of the program “Creation of Research Infrastructure, Processing of Research Data, and Dissemination of Results from International Educational Research.”

Through a user-friendly and functional interface, users can select variables, apply analysis filters, and visualize results related to literacy in Reading, Mathematics, and Science. It supports – through comprehensive visualizations – the comparative study of variables across countries and the extraction of data for further analysis. It is intended for educators, students, and researchers, making it easier to utilize data in the context of research or educational activities.

The application was developed as part of the project “Creation of Research Infrastructures, Processing of Research Data, and Dissemination of Results from International Educational Research,” with Professor Anastasios Emvalotis of the University of Ioannina serving as the Principal Investigator. It was funded under the Program Agreement between the Ministry of Education, Religious Affairs, and Sports and the University of Ioannina through the Ministry of Education, Religious Affairs, and Sports’ Sectoral Development Program for 2021–2025.
