The purpose of this action research study was to investigate challenges to college success specific for first-generation undergraduate students at a public regional institution, and to improve their lived experiences via a first-generation student intervention in the form of a one-quarter student success course. Data collection in Cycle 1 of this study included semi-structured interviews with ten first-generation students at the institution. The results of the Cycle 1 data analysis included themed categories highlighting first-generation student needs including areas of support, COVID-19 pandemic issues, and additional challenges. A Cycle 2 action step was developed in response to the Cycle 1 identified needs, and in combination with recommendations from available literature, a first-generation student success course was created and taken by twenty-one first-generation students early in their college career at the institution. Data collected from the Cycle 2 action step includes course artifacts, instructor observations and notes, an intake survey, student projects, and four semi-structured interviews of students who successfully completed the course. Findings include the importance of first-generation student interventions addressing issues of both resource knowledge and sense of belonging, that a college course is an appropriate format for this type of student success intervention, and that first-generation students can build a sense of belonging through an examination of their positive attributes, connecting with classmates, seeing first-generation success stories, and finding staff and faculty advocates on campus. Implications for the organization include recommendations for further student interventions and a framework for considering first-generation student support programs.
