Empirically effective As previously mentioned, the current BCCSA COR® audit tool has been empirically proven to produce positive safety outcomes. Ongoing research conducted by the University of British Columbia (UBC) shows that COR® certified employers demonstrated, on average, a 12 per cent decrease in short-term disability, long-term disability, and fatality rate between 2003 and 2016 compared to noncertified employers, and an 11 per cent decrease in the serious injury rate. In a separate study, UBC assessed the predictive validity of the BCCSA COR® audit tool, in order to find out if better audit scores are associated with lower employer injury rates, and whether individual element and sub-element scores on the audit tool are associated with lower injury rates. Findings from the 2019 study support the thesis that overall audit performance is strongly predictive of employer level work injury rates. According to Hsu, the BCCSA MAY 2022
