For all three skills, the OECD report scores the proficiency of 16- to 65-years-olds at five different levels, ranging from Level 1 (able to read short, simple texts) to Level 5 (searching and integrating information from multiple, dense texts). The following table contains scores from a subset of countries, including Japan (scoring highest) and Italy (scoring lowest).
