I-03a: Average Score on International Reading Assessment, by Jurisdiction, 2015

* In the cases of nations with measurably larger and smaller shares than the United States, the difference is statistically significant at the 5% level. Certain jurisdictions in gray had smaller or larger shares, but whether these differences were attributable not to a sampling error but to actual differences in the levels of performance between those nations and the United States could not be determined with a sufficient level of confidence.

“The Program for International Student Assessment (PISA) is an international assessment that measures 15-year-old students' reading, mathematics, and science literacy every three years. First conducted in 2000, the major domain of study rotates between reading, mathematics, and science in each cycle. PISA also includes measures of general or cross-curricular competencies, such as collaborative problem solving. By design, PISA emphasizes functional skills that students have acquired as they near the end of compulsory schooling. PISA is coordinated by the Organization for Economic Cooperation and Development (OECD), an intergovernmental organization of industrialized countries, and is conducted in the United States by NCES. Data collection for the most recent assessment was completed in Fall 2015.” (Excerpted from the National Center for Education Statistics’ online PISA overview). The PISA scoring scales for reading literacy (and also math and science literacy) range from 0 to 1,000.
