A company achieves COR® certification through participation in training, development of a health and safety program and participation in third-party verification of the implementation of the program – refer to the Four Steps to Certification.  Throughout the certification process, the NLSCA will issue the company a Letter of Good Standing (LoGs) to indicate that they have met the COR® program requirements.  Similarly, once certified, the NLCSA will continue to issue Letters of Good Standing provided that the company continues to meet the COR® maintenance (Internal/External Audit) requirements.
