The Center on Enhancing Early Learning Outcomes (CEELO) was asked to provide information on how other states are approaching the development and implementation of Kindergarten Entry Assessment (KEA) as part of a comprehensive assessment system. Specifically, the request asked for information about KEA measures used by other states, the processes states have used to develop their KEA state policy, and how states are supporting the training and professional development of practitioners and administrators in various settings. This particular state has recently received supplemental Race to the Top-Early Learning Challenge funding to develop a policy to implement a kindergarten entry assessment process. The state implements a four-year-old kindergarten program, and collaborates with other state agencies to support the use of its state's model early learning standards and implement its comprehensive screening and assessment system. Based on CEELO's research, the following recommendations are provided for stakeholders in this scenario: (1) Review the information contained in this resource, and identify specific questions or state examples or resources that would be most helpful for the committee to review in the initial exploration stages of the state's effort to develop KEA policies and approaches; (2) Determine the goals, guiding principles, and purposes for the KEA in relation to the state's goals for children and in concert with a comprehensive approach to early childhood assessment; and (3) Engage in a process of gaining input from all key stakeholders to assure the KEA reflects the priorities of administrators, teachers and parents. An appendix presents "Considerations in Developing, Purchasing or Modifying a KEA." A list of additional resources is also provided.
