Abstract: The Programme for the International Assessment of Adult Competencies (PIAAC) is a worldwide study designed to assess the skills of literacy, numeracy and problem solving in technology-rich environments. Information on how adults use their skills at home, at work and in the wider community were gathered in three rounds: 2008-13, 2012-16, and 2014-18. Twenty-four countries participated in round 1 of the Survey of Adult Skills (PIAAC) and nine countries took part in the second Round of data collection. PIAAC is developed by the Organisation for Economic Co-operation and Development (OECD). It continues the need for assessing literary skills in developed countries. Two such large international surveys were the International Adult Literacy Survey (IALS) and International Adult Literacy and Life Skills Survey (IALLSS). IALS was conducted in 1994, 1996, and 1998 while IALLSS was done in 2003 and between 2006 and 2008.
