Thank you for visiting our administrator and campus staff page! The fact that you're here shows that you truly care about addressing sexual assault on your campus and empowering survivors. You may have heard about Callisto’s innovative solution to address serial perpetration on college campuses and may be thinking:

  • Callisto Vault is a game changer and I want to support or get involved on my campus.

  • I am looking to expand the resources available on campus and I think Callisto Vault would be a great addition.

  • Callisto Vault sounds like a very interesting tool and I have some questions or concerns.


These are all valid thoughts and we designed this page to answer your questions and support your ability to get involved with our work. Let’s start with the WHY of our work. While many campuses are addressing sexual violence through prevention programming and post-assault resources, they often overlook the impact of serial perpetrators. Here is a deeper dive on the issue of serial perpetration:

  • McWhorter et al. (2009) found that 13% of participants engaged in actions that met the definition of attempted or completed rape. Of that 13%, 71 percent engaged in more than one attempted rape with an average rate of 6.5 incidents.

  • Swartout et al. (2015) found that 10.8% of participants reported having perpetrated at least 1 rape from 14 years of age through the end of college.

  • Foubert et al. (2020) found that more than 87% of alcohol-involved sexual assault incidents were committed by serial perpetrators, who committed an average of at least five incidents each.

  • Studies have found that 4-16% of college men admit, on anonymous or confidential surveys, to having committed at least one rape or attempted rape (Lisak & Miller, 2002; Abbey et al., 2012; Thompson et al., 2013).


Although studies about serial perpetration are limited, many administrators have dealt with cases where multiple survivors have named the same offender and struggled to find ways to address harm in a survivor-centered manner. Well guess what? Callisto Vault offers survivors with a .edu email address a confidential and secure way to know if their perpetrator harmed another person, whether or not they choose to report. This can establish a pattern of evidence that has the potential to increase justice and accountability outcomes for those perpetrators who are causing harm – ultimately reducing sexual assault on college campuses.

Frequently Asked Questions

  • Faculty, staff, and students with active .edu emails at any college or university in the United States and its territories have free access to Callisto Vault. This may extend to alumni depending on your campus’s alumni email management policies.

  • Access to Callisto Vault is free and does not come at any cost to your institution. We invite you to create your free account today!

  • No information entered into Callisto Vault is shared with the institution. Callisto and Callisto Vault are not connected in any way to the college/university so a survivor has ultimate control over their next action step(s). 

  • Callisto Vault’s Matching System is unique because it enables survivors who have been harmed by the same serial perpetrator(s) to securely and safely connect to each other, without needing to report or publicly identify themselves. Additionally, survivors can enter into Matching regardless of who the perpetrator is or where the incident occurred, which expands options for those ineligible to file a Title IX complaint.

  • We are very explicit about Callisto Vault not being a reporting service. Use of our services does not prompt any notifications or generate reports to any authorities. Any and all formal actions taken must be initiated by the survivor outside of the platform.

  • Our Legal Options Counselors (LOCs) discuss all available options with survivors including reporting to Title IX and law enforcement, criminal and civil cases, and on- and off-campus resource referrals.

  • Our Legal Options Counselors (LOCs) can provide a general overview of how the Title IX process works and the rights survivors have under Title IX. If a survivor is interested in pursuing this option, our LOCs will direct the student to reach out to their campus Title IX office to learn about the nuances of your campus’s Title IX process and supportive measures available.

  • Yes. We invite you to share information about the resources and Title IX process at your school to help our LOCs better speak to the options survivor’s have on your campus. If you would like to share resources for your campus, please send them to partnerships@projectcallisto.org.
