This bulletin reports facts concerning the salaries, the amount of education, and the amount of experience in teaching of men and of women in public and in private secondary schools in the United States. It shows the typical condition and the variations from it of each fact for each group, and makes certain obvious comparisons between the groups. The author has attempted also to answer the important but somewhat intricate questions concerning the relation of education, experience in teaching, and personal gifts to financial recompense and to efficiency in teaching, of which they are, under certain conditions, a measure. The types and variations in respect to a salary, extent of education, and length of experience in teaching are estimated, for the country as a whole, from the data for approximately five thousand teachers, who were chosen so as to represent impartially the entire teaching staff in each of the groups. They may be easily calculated for the men and women teachers in public high schools of several States separately from the data given in Section IX. The relations of education and experience in teaching to salary are estimated for several States and other significant local units separately. Differences in the cost of living and in other economic conditions make any estimates of these relations for the whole country too ambiguous to be of service. An index is included. Individual sections contain footnotes. (Contains 9 tables and 40 figures.) [Best copy available has been provided.]
