Computer-based assessment (CBA)

The computer-based assessment consists of the following parts, which are all automatically scored:

• Information communication technology (ICT) core: A set of easy basic computer tasks to assess basic functional computer skills necessary to take the main assessment on the computer. 
• Computer-based literacy/numeracy core: A set of short, easy literacy and numeracy tasks to gather information about basic literacy and numeracy cognitive skills of the participants. 
• Computer-based literacy items: The CBA literacy domain consists of 52 items based on the PIAAC definition of literacy. Of these 52 computer-based items, 30 come from IALS/ALL and will serve as linking items to equate results on PIAAC with results from IALS and ALL. The remaining 22 computer-based literacy items were newly created for PIAAC. [More...]
