Strong anti-bullying policies are foundational to effective bullying prevention. The Youth Bullying Prevention Act of 2012 (YBPA; DC Law L19-167) is among the most comprehensive bullying prevention policies across the United States and its territories. The law and its implementing regulations require all schools and youth-serving agencies (including, but not limited to, government agencies, libraries, nonprofits, and community centers) to adopt comprehensive anti-bullying policies, implement thorough reporting and investigation procedures, provide training for staff, and maintain and report incident data. The law further requires the Mayor to provide, on a biennial basis, a report to Council regarding the current implementation of the Act and a summary of the status of bullying in the District of Columbia. This report serves to fulfill this requirement for school year (SY) 2017-2018. Like its previous iterations, this report provides a detailed summary of each educational institution's engagement with the YBPA. In accordance with the YBPA's requirements, the report is divided into two sections: section 1 covers the programs, activities, and policies established as a result of the YBPA; section 2 covers the state of bullying in the District of Columbia. [This report was co-published by the Government of the District of Columbia, Muriel Bowser, Mayor. For the 2015-16 report, see ED586339.]
