Given the increasing workforce diversity globally, individuals face constant challenges to perform effectively, driving organizations to develop employees' understanding and awareness of different cultures. This study focused on cultural intelligence (CQ), an individuals' ability to respond to multicultural situations adequately. The study's purpose was to generate key indicators to monitor and evaluate CQ training effectively based on transfer outcomes to improve employees' preparation to deal with multicultural settings. Cultural intelligence and social cognitive theories formed the theoretical framework. Three qualitative Participatory Action Research (PAR) sessions were designed to respond to the research question: What are the key indicators to monitor and evaluate CQ training transfer effectively? Data were collected using diverse sources from eight multidisciplinary participants (i.e., undergraduates and professionals with a bachelor's degree) purposely selected by a Qualtrics XM questionnaire and analyzed using NVivo 12 Pro. The results revealed at least one key indicator per CQ training outcome. It can be concluded that key indicators aligned with CQ training outcomes are an effective alternative to evaluate CQ training transfer providing tangible results, offering flexibility, and fostering collaborative engagement. The study's main contribution relies on being novel research in the field. The implications suggest a multidisciplinary group generating operational key indicators to deliver unbiased and accurate assessments favoring triangulation and providing robust data. Conversely, the practice recommendations included redesigning the performance outcomes linked with CQ based on organizations' economic activity to define suitable key indicators. Further research could build on the study's results by implementing the generated key indicators to determine validity and reliability and subsequently develop an instrument. Future research could also build upon the tool generated in the study, the technical fact sheet. [The dissertation citations contained here are published with the permission of ProQuest LLC.
