In 2006, several dedicated early childhood professionals began work on the creation of the "Nebraska Core Competencies for Early Childhood Professionals." Representatives from across Nebraska worked together. After the input from various focus groups, the document became public in July of 2007. The current revision process began in late 2016. Core Competencies are what all adults who work with children need to know, understand, and be able to do. With these competencies, adults can support children's development and school readiness in any setting or capacity. The following nine areas of core competencies are presented: (1) Child Growth and Development Competencies; (2) Health, Safety, and Nutrition Competencies; (3) Learning Environments Competencies; (4) Planning Learning Experiences and Curriculum Competencies; (5) Competencies for Relationships and Social-Emotional Guidance; (6) Observation, Documentation, and Assessment Competencies; (7) Partnerships with Families and Communities Competencies; (8) Professionalism and Leadership Competencies; and (9) Administration, Program Planning, and Development Competencies. [For the current revision, the Nebraska Department of Education (NDE) received support from two national organizations: BUILD Initiative and Center for Enhancing Early Learning Outcomes (CEELO). The development of Nebraska's Core Competencies was supported in part by the federal Child Care Development Funds made available through the Nebraska Department of Health and Human Services and Nebraska Department of Education.]
