This Data Point summarizes trends in adult literacy and numeracy skills since the 1990s for the United States and for those countries that participated with the United States in all three international adult literacy studies over the past three decades: Canada, Hungary, Italy, Norway, the Netherlands, and New Zealand. Results in this Data Point…

Recent literature shows that younger cohorts have lower levels of literacy ceteris paribus in Canada, the United States, Norway and other developed countries. Very few explanations are provided to justify the existence of this negative cohort effect. Yet this decline has serious implications for the economy, education system and society. In this…

This article analyses comparative data from the 1994-1998 International Adult Literacy Survey (IALS) and the 2012 Programme for the International Assessment of Adult Competencies (PIAAC). At the micro level, the author considers factors involved in the development of an individual person's literacy from a lifecycle perspective. At the macro level,…

This paper presents findings by the "LEO Survey 2018 -- Living with Low Literacy." It found that in Germany 12.1% of the adult population (aged between 18 and 64 years) have low literacy skills. This paper questions existing assumptions about the everyday life of adults with low literacy. Based on variables on everyday practices, we work…

This paper illustrates similarities and differences between two international surveys that assess adults' skills: the Programme for the International Assessment of Adult Competencies (PIAAC) and the Skills Towards Employment and Productivity (STEP) survey. In particular, the paper highlights the issues that can arise for researchers interested to…

The field of Adult Literacy and Numeracy (ALN) has an evidence problem. This paper analyses that problem through the lens of three overarching types of evidence available to researchers and policymakers: Type 1 evidence, which provides descriptions of the scope of social problems; Type 2 evidence measuring the impacts of programmes addressing…

We assess the relationship between general literacy skills and health status by analysing data from the Programme for the International Assessment of Adult Competencies (PIAAC), an international survey of about 250,000 adults aged 16-65 years conducted by the Organisation for Economic Co-operation and Development (OECD) from 2011-15 in 33…

Expanded international data from the PIAAC survey of adult skills allow us to replicate the IALS-based analysis by Coulombe, Tremblay and Marchand (2004) as well as Coulombe and Tremblay (2006) based on more recent and more comprehensive data on the literacy skills of the adult population. Results from panel estimations over the period 1970-2010…

Background: In Germany, three large-scale surveys--the Level One Study (LEO), the Programme for the International Assessment of Adult Competencies (PIAAC), and the National Educational Panel Study (NEPS)--provide complementary data on adults' literacy skills that can be harnessed to study adults with low literacy. To ensure that research on…

Participation in adult education and training (AET) programs is increasingly important for people of all ages and is necessary to remain competitive in a world experiencing rapid technological advances. Lifelong learning activities are especially important for middle-aged and older adults who intend to work at older ages to ensure they have the…

It is well-known that there are large disparities in academic achievement between children of different socio-economic status (SES) backgrounds. This study examines the evolution of disparities in literacy skills between adults of different SES backgrounds. It compares countries' patterns in the evolution of disparities in literacy by SES…

This study uses the PIAAC data to examine the relationships between education system characteristics (e.g. early tracking and vocational education orientation) and distributions of adult numeracy skills. It also investigates the effects of postponing the tracking age and easing university access for students on a vocational track on the average…

In designing policies and programmes targeting populations with poor literacy skills, it is important to take into account differences in the level of these skills within and among these populations. For example, native speakers of the mainstream language may require different language-development training than non-native speakers; and most adults…

Using novel adult skills surveys, this article analyses cross-country patterns in skill achievement and labour market returns, comparing the outcomes for a subset of developing countries with the results previously found for high-income economies. Apart from displaying lower average cognitive skills, developing countries also exhibit wider…

This paper offers a comprehensive analysis of the information from the Survey of Adult Skills (PIAAC) regarding adults with low literacy and numeracy proficiency. The paper first describes the demographic and socio-economic characteristics of these populations. Although, they are more likely than the rest of the population to exhibit certain…
