The Standard · Core Mandatory Layer

The foundation for every Organisation

The CML establishes the common governance, legal, horse-wellbeing, environmental, social and economic responsibilities that apply to every SEI-certified organisation. It is combined only with the Activity Modules relevant to what the organisation actually does.
