Campus Climate Survey Validation Study Abstract Presents the results of a nine-school pilot test that was conducted to develop a campus climate survey that collects school-level data on sexual victimization of undergraduate students. The report describes the development of the survey instrument and procedures for data collection, nonresponse bias analysis, weighting, and validity assessment. It presents estimates for each school on the prevalence and incidence of sexual assault, rape, and sexual battery during the 2014–15 academic year, as well as characteristics of the victims and incidents. It also provides estimates of the prevalence of sexual assault since entering college and during the student’s lifetime. In addition, the report examines the relationship between measures of campus climate and rates of sexual victimization. ii Campus Climate Survey Validation Study Table of Contents Section Page Abstract . ii Executive Summary .
