Postgraduate engagement in delivering outreach activities is more commonplace than it once was. However, the impact on postgraduate students (typically studying for a Ph.D. degree) of participating in the delivery of these outreach activities has rarely, if ever, been recorded. The Bristol ChemLabS Outreach program has been running for ca. 17 years, and in that time, many postgraduate students have been involved (approximately 500), with around 250 typically for up to 3 years. We sought to investigate the impact of outreach engagement on postgraduate alumni who were involved in the program for over 3 years (32) and how the experiences and training of the outreach program had impacted on their careers postgraduation. Thirty of the 32 postgraduates engaged and ~70% reported that their outreach experience had influenced their decision making on future careers. Many respondents reported that the skills and experiences gained through outreach participation had contributed to success in applying for and interviewing at their future employers. All respondents reported that outreach had helped them to develop key skills that were valued in the workplace, specifically, communication, teamwork, organizational skills, time planning, event planning, and event management. Rather than a pleasant distraction or an opportunity to supplement income, all participants noted that they felt there were many additional benefits and that this was time well spent. Outreach should not be viewed as a distraction to science research but rather an important enhancement to it provided that the program is well constructed and seeks to develop those delivering the outreach activities.
