This descriptive survey report analyzes data from a nationally representative sample of public school teachers. The first section of the report compares teachers who moonlight during the school year or who moonlight during the summer recess with, respectively, those teachers who do not moonlight during the school year or do not moonlight during the summer recess. Moonlighters are compared with non-moonlighters on a variety of measures, including demographic characteristics, educational background, teaching characteristics, time use, and salary. The survey reveals that moonlighters are more likely to be male, are somewhat younger, and have less full-time teaching experience than their non-moonlighting counterparts; secondary school teachers are more likely to moonlight than elementary school teachers; and while there is no salary difference between school-year moonlighting and non-moonlighting teachers, summer-recess moonlighters earn somewhat less under their primary contracts than summer-recess non-moonlighters. Data are presented in graphs and tables accompanied by narrative discussion. (JD)
