The Program for International Student Assessment (PISA) is a means by which to compare the performance of students around the globe. It is administered in over 70 countries. During the 2009-2010 academic year, more than 200 Clayton High School sophomores participated in PISA testing. Of that group, the results of 176 students were eligible for consideration in the international comparison (students must be 15 years of age). Test results placed Clayton sophomores as first in the world in reading, and second in the world in math (only behind Singapore). PISA began in 2000 and is only administered every three years. Clayton High School was the only local district in Missouri to participate.
