This document is the fruit of a collective effort involving the international contractor for Cycle 2 of PIAAC, the members of the expert groups guiding the development of the assessment in the domains of literacy, numeracy and adaptive problem solving and the OECD.
The literacy framework was developed by the PIAAC Cycle 2 literacy expert group (LEG) under the leadership of Jean-François Rouet (Centre national de la recherche scientifique [CNRS], University of Poitiers, France). The members of the expert group contributing to the development of the literacy framework were Mary Anne Britt (Northern Illinois University, USA), Egil Gabrielsen (University of Stavanger, Norway), Johanna Kaakinen (University of Turku, Finland) and Tobias Richter (University of Würzburg, Germany).
The numeracy framework was developed by the PIAAC Cycle 2 numeracy expert group (NEG), chaired by Dave Tout (Australian Council for Educational Research, Australia). The members of the expert group contributing to the development of the numeracy framework were Isabelle Demonty (University of Liège, Belgium), Javier Díez-Palomar (University of Barcelona, Spain), Kees Hoogland (HU University of Applied Sciences Utrecht, the Netherlands), Terry Maguire (National Forum for the Enhancement of Teaching and Learning, Ireland) and Vince Geiger (Australian Catholic University, Australia).
The adaptive problem-solving framework was developed by the PIAAC Cycle 2 adaptive problem solving expert group, chaired by Samuel Greiff (University of Luxembourg). The members of the expert group contributing to the development of the adaptive problem solving framework were Art Graesser (University of Memphis, United States), Dragos Iliescu (University of Bucharest, Romania), Jean-François Rouet (CNRS, University of Poitiers, France), Katharina Scheiter (University of Tübingen, Germany) and Ronny Scherer (University of Oslo, Norway), with assistance from Juliana Gottschling (University of Luxembourg) and Jan Dörendahl (University of Luxembourg).
