<p>"Students who had learned much more in kindergarten were more likely to go to college than students with otherwise similar backgrounds. Students who learned more were also less likely to become single parents. As adults, they were more likely to be saving for retirement. Perhaps most striking, they were earning more.</p>
<p>All else equal, they were making about an extra $100 a year at age 27 for every percentile they had moved up the test-score distribution over the course of kindergarten. A student who went from average to the 60th percentile — a typical jump for a 5-year-old with a good teacher — could expect to make about $1,000 more a year at age 27 than a student who remained at the average. Over time, the effect seems to grow, too…</p>
<p>The crucial problem the study had to solve was the old causation-correlation problem. Are children who do well on kindergarten tests destined to do better in life, based on who they are? Or are their teacher and classmates changing them?..</p>
<p>When I asked Douglas Staiger, a Dartmouth economist who studies education, what he thought of the new paper, he called it fascinating and potentially important. “The worry has been that education didn’t translate into earnings,” Mr. Staiger said. “But this is telling us that it does and that the fade-out effect is misleading in some sense.”</p>
<p>Mr. Chetty and his colleagues — one of whom, Emmanuel Saez, recently won the prize for the top research economist under the age of 40 — estimate that a standout kindergarten teacher is worth about $320,000 a year. That’s the present value of the additional money that a full class of students can expect to earn over their careers. This estimate doesn’t take into account social gains, like better health and less crime.", [Study</a> Rethinks Importance of Kindergarten Teachers - NYTimes.com](<a href=“Study Rethinks Importance of Kindergarten Teachers - The New York Times”>Study Rethinks Importance of Kindergarten Teachers - The New York Times) .</p>
