There are more than 19,000 nonprofit organizations devoted to supporting public education in the United States. These organizations include booster clubs, parent-teacher groups, public education funds, scholarship funds, high school alumni associations, and others. This report assesses the current status of education support organizations; provides details on the activities, capacities, and resources of public education funds; and compares Public Education Network member organizations with other types of education funds. On the basis of a survey of public education funds and an analysis of the latest data available from the National Center for Charitable Statistics, the report identifies key similarities and differences among the groups. The methodology, definition of regions, and survey questionnaire are appended to this report. (Contains 13 tables, 13 figures, and 9 footnotes.)
