NS is transparent about its performance. Every month, it reports via www.ns.nl on the latest scores for the KPIs that have been set for the main rail network franchise, with detailed supporting evidence. NS is included in the permanent research group of the 250 largest Dutch organisations for the Transparency Benchmark. This is a tool provided by the Ministry of Economic Affairs for improving corporate sustainability reporting within the Netherlands. The results are presented in a Transparency Ladder that is made publicly available and widely communicated. In 2019, NS's 2018 Annual Report came out in third position on the Ladder. The annual report was also nominated for the Sijthoff Prize awarded by the Financiële Dagblad newspaper.
