Jeff Bernstein on 17 Jan 12Here are some obvious conclusions from the study: Teachers are really important. They make a lasting difference in the lives of their students. Some teachers are better than other teachers. Some are better at raising students' test scores. The problems of the study are not technical, but educational. The Chetty-Friedman-Rockoff analysis points us to an education system in which tests become even more consequential than they are now. Teachers would work in school systems with no job protection, and their jobs would depend on the rise or fall of their students' test scores.
