There is much more variation at the bottom of the proficiency distribution, however. An average of 41% of low-educated adults reported having no experience at all with ICTs, or failed the ICT core test. This share ranges from more than 70% in Korea, Poland and the Slovak Republic, and around 60% in Chile, Israel, Singapore, Slovenia and Turkey, to 48% in Greece, and below 20% in a large number of countries, including New Zealand, Norway and Sweden. These three domains are key information-processing competencies that are relevant to adults in many social contexts and work situations. They are necessary for full integration and participation in the labour market, education and training, and social and civic life. This information includes participation in activities that use the competencies assessed in the three domains, such as the frequency of reading different kinds of material or using different types of information and communications technology (ICT).
