What leads to success in school? Every three years,15-year-old students in secondary sit down to take the same exams in reading ,mathematics,and science. The PISA (Programme for International Student Assessment)Collects and studies the results from sixty-four to seventy countries. Countries that usually do the best on these tests are Finland,Korea, and Singapore. Because the global economy is becoming more competitive, educators and governments worldwide are paying close attention to these tests to find how their countries compare-and to learn how they can improve. What are these countries doing right? Should all countries follow their example? Is it possible to follow their example?
