Abstract
Undergraduates make up a critical portion of STEM research workers at universities. However, undergraduate researchers coming from racial, cultural, socioeconomic, gender, or other groups that are historically underrepresented in STEM (i.e., excluded identity [EI]; Bhatti, 2021) often have difficulty accessing professional development opportunities that might encourage them to pursue a career in a STEM field (Barber et al., 2020). To support EI students and increase retention in STEM beyond the undergraduate level, opportunities to build scientific skills should have a low barrier to entry and provide ample training.
