The career concern differences between undecided and decided college students (N = 223) are examined. Undecided college students (n = 83) reported lower career decision-making self-efficacy, higher incidences of negative career thoughts, and more career decision-making difficulties than their decided peers (n = 143). Results reveal that undecided students are as ready to make a career-related decision as their decided counterparts but may lack or be receiving inconsistent career information. Academic advising implications include ways to more effectively serve these populations. Practical suggestions from social-cognitive career theory and the cognitive information-processing approach are provided.
