Novel Länder comparisons (i.e., novel comparisons across German federal states [Länder])

If a research project implies novel and hitherto unpublished comparisons across German Länder (federal states), the application will take longer to process because the project will have to be subjected to scientific peer review. For further details please see the regulations on novel Länder comparisons requiring a more detailed application (approx. 20 pages) for the scientific peer-review process.

Novel Länder comparisons are only meaningful and permissible with data that have been collected for the purpose of national or international monitoring of education and that have representative samples at federal state level.

The following national school performance studies and national supplements to international school performance studies are available at the FDZ and contain representative data at federal state level. Thus, these Scientific Use Files (SUFs) are also available for novel Länder comparisons:

• national supplements to the Internationale Grundschul-Lese-Untersuchung / Progress in International Reading Literacy Study 2001 (IGLU-E):
  • IGLU-E 2001
  • IGLU-E 2006
• IQB National Assessment Studies (IQB-LV):
  • IQB-LV 2008/2009
  • IQB-LV 2011
  • IQB-LV 2012
• IQB Trends in Student Achievement (IQB-BT):
  • IQB-BT 2015
  • IQB-BT 2016
  • IQB-BT 2018
• national supplements to the Programme for International Student Assessment (PISA-E):
  • PISA-E 2000
  • PISA-E 2003
  • PISA-E 2006

The FDZ team will be happy to guide and assist you through the application procedure.
