Teachers who Influence high Academic Performance in Students - Page 2
The research involved a collaboration of economists from Harvard and Columbia University. The studies tracked a large group of cohorts from elementary school to early adulthood for a period of 25 years using two different data sets. The first data set involved:
• 2.5 million students for the years 1991-2009
• 18 million test scores on Math and Reading
The second data set, gathered from the United States (US) federal income tax returns, provided a rich socio-economic background of the cohorts achieving their milestone into adulthood.
The study established the fact that test scores are a pretty good predictor of long-term successful outcomes.
Chetty admits that the research, when viewed outside of other influencing factors, is inconclusive, but when taken in context, he and his colleagues assert “…great teachers create great value, and that test score based value-added measures are one useful input into identifying such teachers.”
