The Big Five personality model identifies five main supertrait facets of personality and their numerous subfacets that culminate into an explanation of an individual’s personality and expression of their behavior. Recently, Angela Duckworth, PhD has conducted studies that demonstrate an individual characteristic that ultimately determines if a person will reach, or even exceed, their goals and become successful in their life endeavors. Grit is described as the dedicated commitment to reaching long term goals. The element of Grit and its strong correlation to the subfactors of Perseverance of Effort and Consistency of Interest has shown a positive relationship in the retention of long-term goals and a clear and concise focus on a subject matter. Although the concept of grit is fairly new it has generated a number of skeptics and regarding its construct validity. The factor structure has not been replicated and its personality underpinnings have not been explored. The current study is an attempt at replication of the factor structure and identification of a nomological net of Big Five factors and personality facets . The study consists of 220 MBA students at multiple universities who took the Big Five assessment, The Workplace Big Five Profile, and the Grit scale. The findings confirm the existence of the factor structure and a number and pattern of personality facets including some not previously discussed in the literature.
