 (February 1, 2012) Harvard University economists Raj Chetty and John Friedman and Jonah E. Rockoff of Columbia University recently released a paper entitled “[The Long-Term Impacts of Teachers: Teacher Value-Added and Student Outcomes in Adulthood.](http://www.rajchetty.com/chettyfiles/value_added.htm)” Tracking one million students from elementary school to adulthood, the authors find that high “value-added” teachers -- teachers who systematically raise their students' test scores -- improve their students' earnings, reduce teenage pregnancy rates, and increase college attendance rates. The study received widespread attention in the media, including a New York Times front-page story in early January 2012, a New York Times opinion column by writer Nicolas Kristof, and a PBS Newshour interview. New York City Mayor Michael Bloomberg cited the study in his [2012 State of the City Address](http://www.nyc.gov/portal/site/nycgov/menuitem.c0935b9a57bb4ef3daf2f1c701c789a0/index.jsp?pageID=mayor_press_release&catID=1194&doc_name=http://www.nyc.gov/html/om/html/2012a/pr014-12.html&cc=unused1978&rc=1194&ndi=1), as did President Barack Obama in his 2012 State of the Union Address in his remarks on improving education in the U.S.
