This document discusses outcome-based evaluation and provides examples from Vancouver Public Library programs. Outcome-based evaluation assesses the effectiveness of programs by tracking qualitative and quantitative changes in the community. It is most useful for evaluating a program's goals, effectiveness, and impact. The document summarizes evaluations of the Alligator Pie early literacy program, Aboriginal Storyteller in Residence program, and Vancouver Inspiration Pass program. Evaluations found that Alligator Pie and the Storyteller increased literacy and social skills, while the Pass increased cultural participation and community connectedness especially for low-income residents. The toolkit for outcome-based evaluation is available online.
