Methodological guidelines
The methodological guidelines for all KPIs are designed to ensure international comparability between KPI values while taking into account feasibility and affordability for the Member States. To that end the methodological guidelines have been defined in such a way that accurate and representative results can be obtained for all parameters of interest defined in the Commission staff working document “SWD 283”. The guidelines include clear specifications of the minimum requirements, which already include some compromises with respect to the initial specifications of the Commission. The methodological guidelines also include guidelines for the minimum sample size and the number of observations.
