Trusting and supportive relationships with school counsellors can help first-generation college students access college despite barriers. In this narrative inquiry, 11 first-generation college students in the United States shared stories of their positive relationships with their former high school counsellors. After an iterative and consensus-based data analysis process, we summarised our participants' grand narrative with five themes: family context, school counselling delivery, relationships with school counsellors, impact of relationships with school counsellors, and suggested improvements. Participants valued how school counsellors helped them advocate for themselves, build their confidence, and feel encouraged and accountable through individual meetings, career counselling, and college guidance. School counsellors can offer targeted and relational interventions to help first-generation college students access and persist through college.
