Looking at the PISA 2015 results that were released by the National Center for Educational Statistics it shows that there has been a drop in average math literacy scores among 15-year-olds since 2009 (pre-Common Core).
The U.S. average score in mathematics literacy in 2015 was 12 score points lower than the average score in 2012 and 18 score points lower than the average in 2009, but was not measurably different than the average mathematics literacy scores in 2003 and 2006.
I should add than in 2015 only 6 percent of 15-year-olds in the U.S. taking the test scored proficiency level 5 or above with 29 percent at level 2 or below.
Massachusetts’ average score was 30 points higher than the U.S. average – 500 to 470. If Massachusetts were ranked as a separate nation it would have been in 20th place compared to the U.S. that is tied for 40th place with Israel. Massachusetts saw a 12 point drop since 2012.
U.S. PISA scores in science literacy and reading literacy were not measurably different than in previous years. It should be noted that Massachusetts scored 33 points higher in science – 529 to 496 and 30 points higher in reading – 527 to 497. Comparing Massachusetts to other nations would be tied for 6th place in Science and 2nd place in reading.
Before Common Core Massachusetts PISA scores were among the best in the world as well. Considering how well they scored in science it is odd they are dumbing their science standards down. Their performance in reading has not been diminished due to Common Core, but nationally we have not seen improvement.
