In 2014 the Oregon 4-H program adopted a new program model to describe and evaluate the impact of 4-H on youths. The model is based on promoting thriving in young people, with an emphasis on high program quality. This article discusses the impact on thriving in 378 youth participants of the 4-H Summer Conference (4-HSC) program. The results of the study conducted provide preliminary support for the validity of the program model as well as the impact of the 4-HSC program on participants. Additionally, the study has implications for the use of program models in translating research into practice across Extension programs.
