Louisiana has conducted its first statewide survey of public college campuses on issues of violence and sexual assault. But so few students participated that the findings don't provide much insight into campus safety.

A 2015 state law required the campus climate survey. Colleges administered it in the spring. Participation is voluntary for students.

The findings were presented Thursday to the Board of Regents, which oversees the law's efforts to improve the way colleges handle sexual assaults.

The board was warned against generalizing the findings. Only 5 percent of college students bothered to take the survey — a response rate that it isn't a representative sample of students.

Regents will try to boost participation next spring by shrinking the number of questions and seeking incentives for students to take the survey.
