The Oregon Health Authority Public Health Division undertook a formative evaluation of the OKHS training and resources on behalf of the OKHS coalition. A formative evaluation is conducted while an intervention is forming to monitor implementation with the intention of further developing and improving the intervention. The specific goals of the OKHS formative evaluation were to understand the: (a) utility of the suite of training, paper-based and online health and safety materials to early care and education (ECE) providers, (b) reach of the OKHS program materials (e.g., who is using them, and in what formats), and (c) users' reactions to the materials. Evaluation results will help inform future decisions about the use of OKHS, marketing and outreach needs, and future program refinements. (author abstract)
