Sampling can be used for: - The two common longer-term result indicators: EECR05 (Participants in employment 6 months after leaving) and EECR06 (Participants with an improved labour market situation 6 months after leaving). To be considered fully reliable, indicator values based on representative sampling are to be reported with a margin of error not exceeding 3 percentage points using a 95% confidence level for a proportion (i.e. a confidence interval of length 6 percentage points). The sample must reflect the characteristics of the population covered by the indicator(s) across the following variables: employment status, age group and education level. The sampling design, method of sample selection and actual sampling methods should be fully documented. - 6 common output indicators under point 1.2 of Annex I of the ESF+ Regulation: EECO12 (Participants with disabilities), EECO13 (Third country nationals), EECO14 (Participants with a foreign background), EECO15 (Minorities), EECO16 (Homeless), and EECO17 (Participants from rural areas). According to the Regulation, if data for these indicators is not collected from administrative registers, values on these indicators can be determined based on informed estimates. Therefore, if the related characteristic is not an eligibility criterion for participation, informed estimates are acceptable. As representative sampling is a type of informed estimate, this method can be used for these indicators as well. Whatever the method used, it should be documented. For the rest of the indicators on participants, it is necessary to obtain data for each participant (either directly or by using administrative registers).
