Software for IEA data

We currently offer two software applications that will allow you to analyze, view, and explore data from our studies. They are the IDB Analyzer and the Data Visualizer. You can also access data through the National Center for Education Statistics (NCES) International Data Explorer. Select the software you prefer and obtain the data you need.

IDB Analyzer
Allows you to combine and analyze data from different countries and select specific subsets of variables. It creates SPSS code.

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.

NCES International Data Explorer
Developed by the NCES, this software lets you explore TIMSS and PIRLS data.

Aggregated and complementary data
