"From Statehouse to Schoolhouse: Anti-Bullying Policy Efforts in U.S. States and School Districts," examines the anti-bullying policies of all 13,181 school districts across the country. It provides the prevalence of anti-bullying policies in all U.S. school districts and whether state laws and guidance are being implemented at the district level. In addition, the report explores whether district policies: (1) protect students specifically on the basis of personal characteristics, such as sexual orientation, gender identity/expression, race and religion; (2) require professional development for educators on bullying and district accountability for incident reporting; and (3) have an impact on school climate for lesbian, gay, bisexual and transgender students. An appendix contains supplementary tables. A list of notes and references is included.
