Table 1.2
Numeracy — Description of proficiency levels
Table summary
This table displays the results of numeracy — description of proficiency levels. The information is grouped by level (appearing as row headers), score range, percentage of the population aged 16 to 65 and characteristics of numeracy tasks (appearing as column headers).
Level Score range Percentage of the population aged 16 to 65 Characteristics of numeracy tasks
5 376-500 1% of populations across OECD and 1% in Canada can successfully perform tasks at Level 5 Tasks at this level require the respondent to understand complex representations and abstract and formal mathematical and statistical ideas, possibly embedded in complex texts. Respondents may have to integrate multiple types of mathematical information where considerable translation or interpretation is required; draw inferences; develop or work with mathematical arguments or models; and justify, evaluate and critically reflect upon solutions or choices.
4 326-375 13% of populations across OECD and 13% in Canada can successfully perform tasks at least at Level 4

12% OECD
Tasks at this level require the respondent to understand a broad range of mathematical information that may be complex, abstract or embedded in unfamiliar contexts. These tasks involve undertaking multiple steps and choosing relevant problem-solving strategies and processes. Tasks tend to require analysis and more complex reasoning about quantities and data; statistics and chance; spatial relationships; and change, proportions and formulas. Tasks in this level may also require understanding arguments or communicating well-reasoned explanations for answers or choices.
3 276-325 48% of populations across OECD and 45% in Canada can successfully perform tasks at least at Level 3

35% OECD
Tasks at this level require the respondent to understand mathematical information that may be less explicit, embedded in contexts that are not always familiar and represented in more complex ways. Tasks require several steps and may involve the choice of problem-solving strategies and relevant processes. Tasks tend to require the application of number sense and spatial sense; recognizing and working with mathematical relationships, patterns, and proportions expressed in verbal or numerical form; and interpretation and basic analysis of data and statistics in texts, tables and graphs.
2 226-275 81% of populations across OECD and 77% in Canada can successfully perform tasks at least at Level 2
