Evaluation has become a standard for youth programming, to provide both evidence for improvement recommendations and an assessment of program outcomes. Having a common evaluation tool across programs (in this case, camps) is beneficial in aggregating measurements and understanding similarities and differences between programs. The purpose of this paper is to describe the process of working with the California 4-H Camping Advisory Committee to develop a common evaluation tool for all California 4-H camps, and to share initial findings from the instrument. We present results from two years of data collection, and the multiple uses of the findings.
