A considerable body of research suggests that knowledgeable and skilled educators are key to the quality of early childhood services. However, the skills and knowledge of educators is subject to being underestimated and contested. In response, the Exemplary Early Childhood Educators at Work Study has been designed to bring to light the distinctive nature of the work of early childhood educators and its complexity. The study draws its sample from centre based early childhood services that are rated as high quality by the Australian Children's Education and Care Quality Authority (ACECQA).
