A “gap year” (sometimes referred to as “Post-Bacc” or a “growth year”) is the period between the end of a student’s undergraduate education and the start of health professional school and often exists because a student needs more time after graduation to strengthen their metrics (GPA, admission test score) or experiences (volunteerism, shadowing, leadership, research, etc.) to become a more competitive applicant. A gap year might be a year or more, depending on each person’s particular circumstances.
