The test, which is given every three years, measures a 15-year-old student’s reading, mathematics and science literacy, according to the National Center for Education Statistics. Results showed that, over all, Americans who took the test scored slightly above students from peer nations in reading.
However, American students scored below the middle of the pack in math, and nearly one-fifth of the students who took the test scored so low it seemed some had not mastered the reading skills of someone far younger. American students’ results in reading and math have also been stagnant since 2000, and the achievement gap in reading between high- and low-performing students is widening.
There is no consensus on why Americans have not made much progress, and commenters, including teachers and former educators, shared their opinions on the matter.( NYT)
