The S2M Certification is a programme of corporate improvement, verification and recognition, which has three components: Sustainability, Measurement and Mediation. The Sustainability component uses the Classic SSR Assessment and an 80% score is required for certification. The Measurement component uses the EvalHexa® Tool to assess the impact of two SSR projects (one internal, one external). The Mediation component uses the Stakeholder SSR Dialogue HexagonTool® to formulate project priorities and assess SSR progress. Initial certification normally takes 1-2 years and results in a public S2M Certification Achievement Award, with annual recertification.
