This article is looking at differences and similarities between the Nordic results in literacy and numeracy in PIAAC 2012 (Programme for the International Assessment of Adult Competencies) and PISA 2000, 2003 and 2009 (Programme for the International Student Assessment). It is important to underline that even though the two surveys are close to each other in defining the skills being measured, there are differences between the two assessments: PISA seeks to measure how well 15 years old students approaching the end of the compulsory schooling are prepared to meet the challenges of today’s knowledge societies; PIAAC focuses on how adults (16–65) maintain and use their basic skills. Despite these differences, the comparisons of the ranking of Nordic results reveals that the overall patterns of performance on the literacy scales are quite consistent for the age-cohorts being compared. Finland is outperforming the other Nordic countries in both studies. The comparison of numeracy results (PISA 2003 and PIAAC 2012) reveals almost the same pattern; Finland scores significantly higher than their neighbor countries, but here the country ranking is slightly changed.
