This report contains evaluation findings from 43 programs that received a total of around $10 million state investment through Proposition 10 to support early childhood services in Kern County, California during Fiscal Year 2017-2018. The Kern County Children and Families Commission (First 5 Kern) was established on December 15, 1998 by Ordinance G-6565 of the Kern County Board of Supervisors to administer the state trust funds from a 50 cent-per-pack tax on cigarette and other tobacco products. For justification of Outcome-Based Accountability, First 5 Kern is expected to provide an annual report on the return to state investment in Child Health, Family Functioning, Child Development, and Systems of Care. A five-chapter structure has been incorporated in this report to evaluate the funding impact on child well-being this year: Chapter 1 highlights features of First 5 Kern support at the Commission level; Chapter 2 provides program-specific findings that impact children ages 0-5 and their families; Chapter 3 describes results of partnership collaboration to strengthen the system building for service integration; Chapter 4 includes longitudinal results from the Core Data Elements (CDE) survey and Family Stability Rubric (FSR) to describe sustainable accomplishments through the ongoing service improvements. This report ends with Chapter 5: Conclusions and Future Directions to review past recommendations and introduce new recommendations for next year. Both qualitative and quantitative approaches were taken to address three key questions: (1) How much has been done in local child support; (2) How well did the programs perform this year? (3) Are any children and families better off? The report includes two appendices, 31 figures, 78 tables, and 129 reference items.
