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.
