How do you ensure the validity of the scoring process?

The final scoring of the companies is the result of scoring by the analyst in charge of measuring the company and verified by the analyst in charge of each technical area. Finally the scoring is checked a third time by two senior analysts at RiskMetrics, the research and analysis provider for the Index.

A statistical analysis has been carried out on the final scores to check for significant correlations between different indicators and the distribution of each indicator. Based on this analysis, adjustments were made to some indicators scoring guidelines to ensure maximum variability. In addition some indicators with high correlation were marked for possible removal in the next iterations of the Index.
