How well are colleges counting sexual assaults that occur on their campuses? This paper provides two measures, the Assault Reporting Ratio (ARR) and the Reporting Rate per 10,000 students (R10K), that address this question. The ARR and R10K are benchmarks that identify institutions that are leading in this area. The measures facilitate comparisons across institutions and over time. The measures enable administrators and researchers to evaluate the effectiveness of institutional policies and practices that govern the reporting of sexual assault. The Clery Act requires institutions of higher education to notify the Department of Education annually about the number of crimes reported on their campuses. The present analysis uses Clery Act data on forcible and non-forcible sexual offenses to create measures that allow a standardized comparison of institutions. The analysis includes adjustments for gender ratio and institution size. National survey results are used to calculate expected assault numbers, which are then compared to institutional reporting numbers to create the ARR. The ARR is expressed as a percentage. An ARR of 100% indicates that the school is counting all of the assaults predicted by national surveys. The R10K is the reported number of assaults per 10,000 students, calculated from the data provided by the institution. A total of 1,230 schools were used in the analysis; of those 30.7% reported no sexual offenses. The mean Assault Report Ratio (ARR) was 2.54% (7.4) with a median of 0.93%. The mean Reporting Rate per 10,000 (R10K) was 7.47 (22.22) with median of 2.94. Ranking tables of the Top 20 institutions, overall and stratified by enrollment, are given. The standardized measures can be used to evaluate institutional policies, changes in programs, and procedures for reports. Attachments include ranking of all institutions in analysis by each measure, Excel, and csv delimited data files.
