Universities increasingly make their sales curriculum available for groups other than dedicated sales students. This study investigates engineering students' drivers that predict interest in sales certification, as well as drivers that predict actual choice for a sales curriculum. We focus on engineering students (n = 204) and contrast our findings with business students (n = 179). Based on social cognitive theory, we investigate how personality (Big Five personality factors and Trait Competitiveness), ability (ACT, GPA, and Academic Self-Efficacy), and social factors (role models, and perception of salespersons) affect interest and choice. Our results indicate that although the regression models explain a reasonable amount of variance, models that work for business students do not work equally well for engineering students. Also, our analysis reveals that factors that explain interest do not explain actual choice, and vice versa. In addition, we uncover subtle gender difference when it comes to actual choice for a sales curriculum. Finally, the benefits that engineering students perceive of sales certification differ primarily based on whether students are taking sales classes, and not on degree sought.
