Aims: This article discusses the process, findings and lessons learned from the external evaluation of the Youth Outreach Program (YOP), a three-year intensive outreach and support program intended for at-risk Aboriginal youth, 13-18, with characteristics and/or behaviours associated with Fetal Alcohol Spectrum Disorder (FASD). The overall purpose of the formative and summative evaluation was to document the development and early implementation of the program, in order to make adjustments as the program unfolded; and to assess, describe, and document early outcomes for youth participants and community partners.
