What is Risk Ratio?

Risk ratios compare the risk of an event happening between two groups. In this newsletter, we discuss the relative risk ratio for receiving an office discipline referral (ODR) or out of school suspension (OSS) between students with and without disabilities. 

Measuring Equity

 A risk ratio of 1.0 means that there is equitable distribution between the two groups. A risk ratio over 1.0 means a group is over represented and more likely to experience that event, while under 1.0 means they are less likely to have the event occur. Risk ratios are one way to determine how PBIS systems are impacting students with and without disabilities equitably.
