This guide focuses on the issue of school-based harassment. It is intended to help educators prevent or curtail all forms of harassment by highlighting school-based harassment issues, by describing remedies and prevention strategies, and by providing additional resources. It details some of the problems school-based harassment engenders, and it explores common misperceptions of harassment, as well as its legal implications. The guide features an overview of harassment, offering specific strategies for preventing--and responding to--such harassment. Such tactics include professional development, curricular concerns, and personal considerations for educators. It describes what school employees, families and communities, and students need to know by using a question-and-answer format. The three sections that cover these can be pulled out and used separately. Some of the legal foundations of responses are likewise discussed, and an emphasis on self-reflection is prominent throughout the text. A case study is presented. Online, organizational, print, video, and curricular resources are listed. (RJM)
