As of 2022, one third of college students in the United States are first-generation students (FGCS), with a significant number pursuing engineering degrees. This research focused on understanding and addressing the unique challenges and needs of FGCS in engineering, emphasizing the importance of career and professional development. FGCS often face barriers (e.g., lack of awareness about the college process, financial constraints, limited support networks), which can hinder their academic success and career readiness. These challenges are compounded for engineering students due to additional factors like insufficient exposure to STEM fields and identity-related issues. This study was conducted at a pseudonymized institution, OCX University, with a focus on the school of engineering. The institution, like many predominantly White institutions, has specific challenges related to serving a diverse student body, including FGCS who are often students of color. The research aimed to improve FGCS's career confidence and readiness through a tailored 3-unit course on career and professional development, addressing gaps in existing support services. The study highlighted the need for comprehensive career programming that integrates academic and professional development, ensuring FGCS in engineering are well-prepared for the job market. The findings suggested structured career courses can significantly enhance students' career tools, interpersonal skills, and overall readiness for professional success. The research underscored the importance of strategic institutional support to meet the evolving demographics and needs of FGCS in higher education.
