The World Bank Learning Outcomes Query holds data on levels of student learning in reading, mathematics, science, and problem solving. The query includes data from five international learning assessments (PISA, TIMSS, PIRLS, PIAAC, and EGRA) and three regional learning assessments (SACMEQ, PASEC, LLECE). Mean scores were calculated on a scale with a centerpoint of 500 except 2004-2010 PASEC (0 to 100 scale), 1997 LLECE (250 centerpoint), PIAAC (0 to 500 scale), and EGRA (varying scales). Data may not be comparable across years, countries, languages, or assessments. Each assessment is summarized in the table below, and more detailed information is available through the source links under “About the Data”.
