Audit Scoring

A key element of the IRIS certification’s success is the transparency of both the scheme and the awarding process. Throughout the years, IRIS Certification has proved its value through reliable audit scoring that objectively assesses companies’ quality management systems. Audit scores are of great value in depicting the sector’s state of affairs, allowing a better understanding of its strengths and challenges.

IRIS Certification offers the unique possibility to differentiate the quality performance of individual companies through the implementation of three Quality Performance Levels: Gold, Silver and Bronze. This scoring method creates further incentives for companies to strive towards higher quality objectives, enhancing the quality of the whole rail sector.

See below the IRIS Certification audit score evolution – divisible by chapters, sub-chapters, countries, Quality Performance Levels and more. This section also includes a survey conducted among IRIS Certified companies about their knowledge of the scheme and its requirements.

Audit Score Evolution

See below the evolution of IRIS Certification audit scores since the foundation of the scheme.

As the number of issued certificates rose, it was expected to see a decrease in the global average score until 2014. However, with the introduction of IRIS Certification Quality Performance Levels, the average has now been increasing for the last 7 years as companies are further incentivised to achieve higher performance evaluations during their audit.

The chart below illustrates the global average score evolution, as well as average scores for 5 countries with the highest number of issued certificates - Germany, France, Italy, Spain and China. This can be compared with the average scores achieved by companies awarded Bronze and Silver level certificates.
