Risk Assessment Form

The purpose of this risk assessment is to ensure that the likelihood and possible impact of risks has been considered in the planning of CAS experiences. Once a risk has been identified, steps can be taken to mitigate its likelihood. If there are safety concerns, the risk assessment should be discussed with your Parents and your CAS Advisor before starting the CAS Experience and, if necessary, plans should be changed.
