In reading, math, and science the U.S. was reported to be lagging far behind countries like Finland, Singapore, China and South Korea. Corporate reformers and Arne Duncan have used the results to in part, blame public schools for this country's declining power vis-a-vis it's perceived global competitors. It has also provided the rationale for the labeling of thousands of urban public schools as "failing" or calling them "dropout factories."
But as my colleague reminded me, there were several ways of looking at U.S. PISA data which show that US schools with 10% poverty would score #1 in the world in reading. Those with 25% in poverty would score #3 in the world. And those with 75% students in poverty would score 33rd in the world.
Other high-achieving countries like Finland and Singapore have very few kids in poverty and very equitable outcomes for schools that serve those kids, so it wouldn’t change their rankings much. OECD has documented all this in the PISA reports.
It makes it clear once again that the main difference in measurable learning outcomes between high and low-scoring schools in this country has more to do with parent income than anything going on in the classroom and that student scores can't be used as a reliable measure of schools or teachers.
These figures caused many of my students to wonder, what exactly are our standardized tests really measuring?
