The document discusses referencing the different editions and components of the Early Years Foundation Stage (EYFS). There are two editions of the EYFS published in 2007 and 2008 by the DfES and DCSF respectively, which have some differences. When referencing a specific component, the text should make clear which edition is being referenced. If referencing multiple EYFS components, letters are used to distinguish the different references when they have the same publication date. The document provides examples of how to reference the EYFS in both in-text citations and end references.
