Welcome to the Profit of Education website. Continuing the conversation begun in the book Profit of Education, we discuss the latest economic evidence on education reform.

Teacher attrition

The Department of Education has a “First Look” study out, “Public School Teacher Attrition and Mobility in the First Five Years,” with somewhat surprising numbers on teacher attrition. (Thanks to NCTQ for the link.) The headline number is that only 17 percent of teachers who began in 2007-08 had left teaching by 2011-08. That’s very surprisingly low. A comment below on why I’m not sure I believe it. But first, a quick picture relating the numbers to one of my favorite topics–teacher salaries.

However, one caveat is called for in all this. About three-quarters of teachers surveyed responded to the questionnaire in the first year. By the fifth wave, the response rate was only 56 percent. Do you think those who didn’t respond were disproportionately those who left teaching? I do. That means that headline 17 percent dropout rate could be way, way off. I’ve presented the graph above on the theory that the survey errors for low-paid and better-paid teachers might not be too different. In other words, I suspect both lines below are lower than the truth, but maybe the gap between the two isn’t too far off.
