MATCHING AND LINKING TERMINOLOGY
For the purposes of the National ECEC Collection, match or matching relates to the scenario where two or more records can be identified to belong to the same unique child. Linked or linking relates to the scenario where two or more records are linked but not necessarily a true match for a unique child. For the National ECEC Collection, episode linking methodology uses the Statistical Linkage Key (SLK), which is not a unique identifier. In a majority of cases, the SLK is a unique identifier. However, in some instances, more than one child may have the same SLK due to similar SLKs sharing characteristics. For further information about the SLK please see National Early Childhood Education and Care Collection: Data Collection Guide (cat. no 4240.0.55.002)
