A society becomes more fully conscious of the importance of giving to all its members the best possible education, it also becomes conscious of the great loss arising from truancy of school children and of the need of finding some better means of dealing with truancy. In all cities and towns, as well as in rural communities, school officers and teachers want information about methods of dealing with truants. In the larger cities they want to know about the methods of organizing and conducting parental schools. For the purpose of giving this information, this bulletin provides the following: Part I. A study of 100 typical cases of truancy in Philadelphia; and Part II. A study of parental schools in 13 cities. (Contains 6 figures, 1 footnote, and a Questionnaire used in survey of parental schools.) [Best copy available has been provided.]
