In 2011, the ECE (early childhood education) Taskforce report, An Agenda for Amazing Children, recommended an evaluation of the implementation of the early childhood curriculum Te Whariki. In response, ERO conducted a national evaluation that investigated: How effectively are early childhood services across New Zealand determining, enacting and reviewing their curriculum priorities to support education success for every learner? Findings from this national evaluation are published in two reports. This report, Working with Te Whariki, highlights the different ways services are working with the early childhood curriculum, Te Whariki, and discusses the emerging themes and challenges associated with implementing this curriculum 17 years on from its publication. It complements a companion report, Priorities for Children's Learning in Early Childhood Services (May 2013). (author abstract)
