According to data collected by the Program for International Student Assessment, or PISA, American students continue to slide down the international rankings, failing to break the top 20 best-performing countries as of 2012. U.S. students rank below average in math and near average in reading and science. PISA is just one assessment, but it reflects a clear trend: U.S. students are not achieving what they need to achieve in an increasingly competitive global economy.
