- Occupational health and safety interventions, including regulatory approaches, programs, and management systems, are key strategies for reducing worker injury and illness.
- Certificate of Recognition (COR) audit programs use voluntary audit-based certification as a way of recognizing or encouraging effective OHS practices. COR programs provide premium rebates to employers who meet certain occupational health and safety management benchmarks or who have implemented a return to work program for injured workers.
- We conducted independent impact evaluations of the COR programs in BC and Alberta, to assess how participation has affected firms’ claim rates and health and safety experience.
- Both the BC and Alberta evaluations found that certification is associated with lower injury rates. Detailed results are available in the research briefs at right.
- Our team developed an analytic database of BC Construction Safety Association (BCCSA) COR audits, in order to investigate the effect of the COR program on firm injury claim rates in the BC construction sector specifically.
- We are currently assessing the predictive validity of the BCCSA COR audit tool, to find out if better audit scores are associated lower firm injury rates, and whether individual element and sub-element scores on the audit tool are associated with lower injury rates.
Watch an interview with Chris McLeod, filmed by the Journal of Commerce at the BC Road Builders and Heavy Construction Association Fall Conference 2015, on the results of the COR evaluation.
Watch a plain language video produced by the Institute for Work & Health explaining the main findings of the BC COR evaluation.
