A quarter of adults in Italy have reduced skills in all three cognitive domains: in reading and comprehension of texts, in using mathematical information, and in problem solving in dynamic situations. A report by the National Institute for Public Policy Analysis (INAPP) reveals this. In Italy, 35% of people aged 16-65 have reduced skills (i.e., are low performers) in reading and comprehension of texts (26% in the OECD average). This percentage, also confirmed for skills in using mathematical information (25% in the OECD average), rises to 46% in problem-solving skills in dynamic situations (29% in the OECD average). Analyzing the three domains jointly, the figure stands at 26% (18% in the OECD average): in Italy, about 1 in 4 adults aged 16-65 years has reduced skills in all three cognitive domains (literacy, numeracy and adaptive problem solving). This result varies substantially across the Italian territory: while in the Northeast 13% of the adult population has reduced skills in all three domains, the percentage rises to 19% in the Center, 21% in the Northwest, 40% in the South, and 46% in the Islands. People with high skill levels (the high performers) in our country are significantly fewer: 5% in reading and comprehension of texts (12% in the OECD average), 6% in using mathematical information (14% in the OECD average), and just 1% in problem solving in dynamic situations (5% in the OECD average).
