Callisto is a new college sexual assault recording and reporting web-platform created by nonprofit Sexual Health Innovations (SHI). Callisto was first announced at the White House Data Jam on Protecting Students from Sexual Assault and is partially funded by Google.org. Callisto is designed to address three major issues around campus sexual assault: (1) supporting and empowering student survivors, (2) providing better data to schools around sexual assault on campus, and (3) facilitating the identification of repeat perpetrators. The Problem: One in five women and many men will be assaulted during their college career. It is estimated that less than 10% of survivors will ever report to their campus or local law enforcement, and a mere 2% of survivors who were assaulted while incapacitated report. Additionally, up to 90% of college rapes are committed by repeat offenders, and if these individuals were stopped after their second assault, up to 60% of rapes could be prevented. By providing a safe, supportive and trauma-informed platform for students who have experienced a sexual assault, we hope to increase official reporting rates and reduce the emotional trauma around reporting. By providing students the option to report only if another student reports being assaulted by the same assailant (the 'Matching Escrow'), we aim to increase identification of repeat perpetrators, and provide better evidence to schools and law enforcement in those repeat offender situations. By allowing students to save a time-stamped record of what happened and take their time considering which reporting option(s) is right for them, we aim to improve the quality of memories and evidence that are reported, and increase the likelihood that the school or police is able to take appropriate action. How it works: Callisto serves as a first portal for student survivors to create and save a secure record of what happened, and then access a clear overview of their reporting options and what to expect in the process of reporting. Callisto also connects students to important survivor resources, and allows them to opt into the 'Matching Escrow' to report only if another student names the same assailant.
