In this chapter, we investigate the way in which the ITiCSE working groups serve as a path into computing-education research. Previous analysis has shown that working group participants are both highly collaborative and open to working with newcomers. Newcomers comprise over 50% of group members each year and they are rapidly connected to the larger working-group community. As long as there have been working-group old-timers (since the second year the working groups were held), nearly all working groups have included both newcomers and old-timers. Here, we update this analysis to cover all the in-person working groups through 2019 and look more closely at the nature of these collaborations. Through 2019, we found, working-group members quickly became part of a community, closely connected to the large majority of working-group members, past and present. Working groups give their members the opportunity to work with people they have never published with before, from other institutions and a wide variety of different countries, and to work beside and learn from established researchers in the field. In addition, most working groups lead to some future collaborations by authors who worked together there for the first time.
