Good Teachers Have Lifelong Impacts

The study was done by Raj Chetty and John N. Friedman of Harvard and Jonah E. Rockoff of Columbia. The sponsor is undisclosed in this article. Since the study portrays the importance of quality teachers, the sponsor could be looking for evidence that school districts should use value-added measures in teacher evaluations. Some information regarding methodology is included; 2.5 million students were tracked over 20 years. The results are clear and show the economic benefits of replacing poor teachers with better ones. There are also three scatter plots included in the article; the graphs are easy to read with clear results. The graphs show that students having quality grade-school teachers is positively correlated with the likelihood to attend college and future salary, while negatively correlated with teenage pregnancies.
