Too Many Teachers: 40 Years Of More Teachers And Smaller Classes Have Not Improved Math And Reading Scores Or HS Graduation Rates

From The Wall Street Journal, "Jay Greene: The Imaginary Teacher Shortage: Forty years and a million more teachers later, student performance is unchanged. Yet Obama and Romney both say schools need more staff." by Jay P Greene:
For decades we have tried to boost academic outcomes by hiring more teachers, and we have essentially nothing to show for it. In 1970, public schools employed 2.06 million teachers, or one for every 22.3 students, according to the U.S. Department of Education's Digest of Education Statistics. In 2012, we have 3.27 million teachers, one for every 15.2 students.

Yet math and reading scores for 17-year-olds have remained virtually unchanged since 1970, according to the U.S. Department of Education's National Assessment of Educational Progress. The federal estimate of high-school graduation rates also shows no progress (with about 75% of students completing high school then and now). Unless the next teacher-hiring binge produces something that the last several couldn't, there is no reason to expect it to contribute to student outcomes.

  1. I bet the NEA isn't going to be talking too much about this statistic.
