Good ol’ Eric Hanushek says she just might be:
Over the course of a school year, a good teacher produces $400,000 more in future earnings for a class of 20 students than an average teacher. What’s more, replacing the worst-performing five to eight percent of teachers with average teachers could catapult the U.S. to near the top of international math and science rankings, padding GDP by $100 trillion and generating returns that dwarf “the discussions of U.S. economic stimulus packages related to the 2008 recession ($1 trillion).”
These are the findings of a National Bureau of Economic Research study by Stanford’s Eric Hanushek, which investigates the interplay between teacher effectiveness and the economic impact of higher student achievement, specifically in terms of test scores.
No, really. I love it.
