Stephanie McClure, director of the university's Women's Center, was disappointed by the low participation, but she added that a software error left some student responses uncounted.
Weber State tells students they are expected to take the training, but there is no penalty if they do not. That may change in the coming years, McClure said.
The vast majority of students who took the training last school year were white, heterosexual and 21 years old or older. More than 50 percent of the participants were women.
Under a federal law called Title IX, schools must address sex assault by not only disciplining offenders but also protecting victims and eliminating the "hostile environment" created in the aftermath of an attack. A student who may have been the victim of a sexual assault is entitled to immediate services, such as housing changes and class adjustments or more lenient deadlines.
McClure said university officials work hard to make sure students understand their reporting options.
"My No. 1 priority is for students to understand what forms of conduct are prohibited on campus ... and students have a right to report that," she said. "I want to make sure students know that and are familiar with resources in case something like this does come up for them."
But prevention is important, too, McClure said, making Haven data about bystander intervention useful.
More than 80 percent of Weber State students surveyed said they were willing to intervene if faced with a situation of sexual or relationship violence.
"We've been able to use this data already ... to help encourage students, when you see something problematic around you, you are generally not the only person in the room that feels that way," McClure said. "There's a high percentage chance that they will help you."
Based on reported attitudes and behaviors — including students' alcohol use and their views on healthy sex and consent — Haven divides some of its data into two groups: the healthy majority and the unhealthy minority. The healthy group is more likely female and to abstain from drugs and alcohol, while the unhealthy group is more likely male and members of fraternities or athletes.
More than 90 percent of students in the healthy group showed they understood what sexual assault is, compared with under 65 percent of students in the unhealthy group.
"We can figure out who are the students that need to be targeted with this information," McClure said.
About 80 percent of students in the healthy group said that an individual should not be blamed for being sexually assaulted, compared to less than 60 percent in the unhealthy group.
Additionally, more than 80 percent of healthy group participants agreed that "explicit verbal consent" is the best way to determine if someone wants to engage in sexual activity, compared to less than 65 percent of the individuals in the unhealthy group.
Students currently are taking the 2016-2017 school year Haven training, and there already is more participation than last year, McClure said.
