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.


Sara Champion has written what looks to me to be the best ever paper measuring moonlighting by teachers. I learned a number of interesting facts.

  • Not very many people moonlight. Not very many teachers moonlight either. But teachers are more likely than others to work a second job. About 11 percent of teachers moonlight in “regular jobs” (ones reported to state employment offices in the usual way). Maybe a total of 20 percent moonlight in total.
  • Those who moonlight add, very roughly, 10~ 11 percent to their teaching salary.
  • Low paid teachers are more likely to moonlight.
  • It appears that an hour of extra moonlighting offsets about one hour of teaching work. (We’re talking about unpaid teaching work, not contractually required work.)

And perhaps most interestingly,

  • In schools subject to accountability measures (generally low-performing schools), moonlighting rates fell.
