Working with IEA Data

Below is an overview of free software tools and additional resources which will help you to work with IEA data and data from other international large-scale assessments in education. Please visit our training page for details of the support that we offer researchers.

IDB Analyzer

The IEA International Database Analyzer (IDB Analyzer) is a free software tool which can be used to combine and analyze data from all IEA's large-scale assessments. It can also analyze data from most major large-scale assessments, including those from the US National Assessment of Educational Progress (NAEP), and those conducted by the Organisation for Economic Co-operation and Development (OECD). The IDB Analyzer includes a built-in integrated help file which serves as a technical manual for users. Additionally, all IEA studies publication on the Data Repository include respective users guides that will guide users when working with data.

The IEA IDB Analyzer installation requires the .NET Framework version 4.0 or above. If you intend to install the IDB Analyzer on a machine with Windows 8 or earlier, please make sure you have installed the .NET Framework on your system. The .NET Framework can be obtained from the following website:

User Guides

User Guides for IEA studies contain information on the structure and variables within the data and how to conduct analyses using the IDB Analyzer. Please see our publications database for a full overview of available user guides.

Data Visualizer

The IEA data visualizer enables you to visualize trends in TIMSS and PIRLS data over time. Also lets you visualize data in the form of graphs and world or regional maps.

ILSA Gateway

The ILSA Gateway provides easy access not only to IEA studies but also to major International Large-Scale Assessments (ILSA) conducted by other organizations, including, but not limited to, the Conference of the Ministers of Education of French-Speaking Countries (CONFEMEN), the Inter-American Development Bank (IDB), the Organisation for Economic Co-operation and Development (OECD), the Southern and Eastern Africa Consortium for Monitoring Educational Quality (SACMEQ), and the United Nations Organization for Education, Science and Culture (UNESCO).

The Gateway was created to meet the needs of researchers, policymakers, and decision-makers, as well as officials and staff members from intergovernmental, international nongovernmental, and civil society organizations. It aspires to enhance the exchange of knowledge, to encourage secondary analyses of data, and to strengthen communication within the ILSA community.
