International Data Management Unit

The work of the International Data Management Unit involves reviewing and processing all national data records and creation of the International Data Base (IDB). This department is the point of contact for the participating states in all issues relating to data processing.

The unit is sub-divided into the following sections:

The data management section deals with the development of structures for international data processing. This includes the development of software for random sampling of student questionnaires, entry and verification of data, and the ready provision of this data to the participating states. This section also develops user manuals relating to the programmes and procedures for data management. The international data management section is also responsible for supporting the participating states in all issues relating to data processing.

The data management seminars provide training in how to conduct international IEA studies and in how to use the supporting software.

All national deviations from the international test instruments are recorded and documented by this section.

In order to ensure comparable and reliable data, the data cleaning section examines study data for structural and logical inconsistencies. This section is responsible both for the organisation and conduct of data cleaning and for the development of the software used in this work.

The international data base is developed from national data and accompanying documentation in co-operation with the partners in the consortium.
