Early Learning and Development Standards (ELDS) articulate what young children should know and be able to do prior to beginning kindergarten. In 2013, early childhood experts in North Carolina revised the state's ELDS and released The North Carolina Foundations for Early Learning and Development (Foundations), which articulates standards across five domains for children birth to age five. Since the release of Foundations, numerous programs and agencies across North Carolina have developed different types of professional development opportunities to increase teachers' knowledge and use of Foundations. The purpose of this study is to provide information about the effectiveness of different types and amount of professional development related to ELDS, the extent to which teachers have learned how to use ELDS with children and families, and to identify additional professional development needs and supports teachers' require to be able to use ELDS more effectively. Results from the study will be used by the Child Care Administrator and others to guide plans for professional development to support the use of the ELDS, which is required in the recent reauthorization of the CCDBG Act.
