Requiring a signature on supplier policies or explicitly ensuring that adherence to suppliers policies is part of the contractual trading agreement reinforces the importance of compliance and demonstrates that the company is serious about suppliers' performance on social and environmental issues.
A note on the scoring system
WikiRate has a standardised 10-point scoring system making it possible to compare company scores across different benchmarks. On WikiRate.org, the Fashion Transparency Index scoring system, where each company can get a maximum of 250 points, has been converted to the 10-point scoring system - with 10 being the highest a company can score and 0 being the lowest. These company scores can also be translated to percentages e.g. if a company has scored 2.5 out of 10 on WikiRate, they have achieved 25% of the 250 points in the Fashion Transparency Index.
