What is it?

The R&A benchmarking service available now, free of charge, at bestcourseforgolf.org. There are two services available to use; benchmarking and KPIs:

The KPI system allows you to track your progress from year to year to see any trends or changes that occur, it is designed to be easy and cost-efficient.
The full benchmarking service lets you reference your course against similar courses from around the world. It takes more staff time and knowledge to complete, but offers more information and analysis.
