This week on Banter, AEI’s John H. Makin Visiting Scholar Eric Hanushek discusses the relationship between teacher cognitive skills and student achievement.

Dr. Hanushek’s research finds that there are substantial differences in teacher cognitive skills across countries that are related to student performance. Dr. Hanushek will soon publish a new academic paper in the Journal of Human Resources on the subject. You can read the full paper and listen to Dr. Hanushek’s appearance on the “Political Economy” podcast with Jim Pethokoukis at the links below.
