The OECD Survey of Adult Skills (or PIAAC) measures adult skills and competencies in three key areas: literacy, numeracy, problem solving in technology-rich environments.
Data from the last PIAAC survey indicated that 44% of Australian adults lacked the literacy skills they need for work and to cope with everyday life.
