Grade inflation is rampant and has been so for many years. Back in 2011, an in-depth study by three Ivy League economists looked at how the quality of individual teachers affects their students over the long term. The paper, by Raj Chetty and John N. Friedman of Harvard and Jonah E. Rockoff of Columbia, tracked 2.5 million students over 20 years and, using a value-added approach, found that teachers who help students raise their standardized test scores have a lasting positive effect on those students’ lives beyond academics, including lower teenage pregnancy rates, greater college matriculation, and higher adult earnings. The authors of the study define “value added” as the average test-score gain for a teacher’s students “…adjusted for differences across classrooms in student characteristics such as prior scores.”
