The Department of Defense (DoD) seeks to continually improve upon sexual assault and sexual harassment response programs and resources available to Service members. The 2021 QuickCompass of Sexual Assault Response Personnel (2021 QSAR) product group provides important information to the DoD on sexual assault responders’ training, their access to and relationships with command and other professionals, their perceptions of resources provided to victims, the support they receive in their profession, and their personal wellbeing.. The 2021 QSAR was administered via the web between June 8 and July 20, 2021 and is the fifth survey of this population following four previous iterations conducted from 2009 through 2018.
