Although the United States spends more per student than most other countries, results from the PISA 2012 show that American students ranked below the OECD average in mathematics and around the OECD average in science and reading. OECD also notes that the socioeconomic status of American students has a “notable impact” on their performance. Two reports, Education at a Glance and Strong Performers and Successful Reformers in Education, examine factors specific to the United States related to such results.
