Have you ever thought about whether that one “great” teacher you had in 3rd or 4th grade really changed the course of your life?\u00a0<\/span><\/p>

According to groundbreaking research by Raj Chetty, John N. Friedman, and Jonah E. Rockoff, the answer is a resounding yes, and the effects can be seen in the millions of dollars.<\/span><\/p>

The researchers of the huge study Measuring the Impacts of Teachers followed 2.5 million kids for 20 years to find out exactly how much a good teacher is worth. The results changed the way people around the world talk about education policy and the real worth of “Value-Added” metrics.<\/span><\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Before looking at the results, it’s important to know what the metric is. Value-Added (VA) is a way to use statistics to guess how good a teacher is at their job. It doesn’t just look at raw test scores; it also looks at how much a teacher helps a student do better than they were expected to based on their past results.<\/span><\/p>

Some people used to say that these metrics were “noisy” or biased, but Chetty’s research showed that VA is a very good way to guess how well a student will do in the future.<\/span><\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

The study linked school district data (grades 3\u20138) with federal income tax records to see what happened to these students as adults. Here is what they found:<\/span><\/p>

  1. The Big Money Windfall<\/b><\/li><\/ol>

    The “Million Dollar” Effect is the most interesting thing that came out of the study. The study found that if you replaced a teacher in the bottom 5% of VA with a “average” teacher for just one year, the students in that one classroom would make about $1.4 million more over their lifetimes.<\/span><\/p>

    1. More money and a better job<\/b><\/li><\/ol>

      \u00a0<\/p>

      Students who were assigned to high-VA teachers saw a direct link to their paychecks. These students were making a lot more money than their peers by the time they turned 28. A “high-quality” teacher doesn’t just help a student pass a test; they teach them skills that are useful in the workplace, both cognitive and non-cognitive.<\/span><\/p>

        It wasn’t just about the cash. Students who had the best elementary school teachers were:<\/span><\/p>
