The paper presents findings on secular score gains in Raven’s Progressive Matrices during six decades (1948- 2009) in Polish adolescents. Seven groups are being compared, comprising of 20, 490 subjects in total. The representative groups examined in 2000 (N=1,331) and 2009 (N=3,650) are those of special interest as they are the most numerous and allowing formal means comparison using standard test for comparison of means and Welch’s test. Possible causes for the noted effect are being discussed, with special emphasis on the economic growth and its implications - such as improved nutrition, education changes, growth of adolescent’s well-being and child upbringing practices.

Przez lata wskaźniki zdolności poznawczych i kompetencji akademickich sugerowały, że zdolność ludzi do skutecznego radzenia sobie z otoczeniem ulega poprawie (nazwanej efektem Flynna). Ostatnie dowody sugerują, że ten trend może się zmieniać. To badanie analizuje dane uzyskane z Programu Międzynarodowej Oceny Uczniów (Program for International Student Assessment ) dla celowej próby grupy 9 krajów w ciągu ostatnich 6 lat i sugeruje, że rzeczywiście istnieją dowody na znaczny spadek kompetencji uczniów i umiejętności czytania, pisania i matematyki poza możliwymi względami ekonomicznymi i czynnikami krajowymi. Omówiono znaczenie wyników dla edukacji i jego potencjalne implikacje.

For years indicators of cognitive abilities and academic competencies suggested that humans’ ability to effective cope with their environment is improving (dubbed the Flynn effect). Recent evidence suggests that this trend may be turning. This study explores data obtained from the Program for International Student Assessment for an intentional sample of 9 countries over the last 6 years and suggests that indeed there is evidence of substantial decrease in students competencies and literacy in Language (writing) and Math beyond possible economical, and national factors. The relevance of the results to education and its potential implications are discussed.
