The purpose of this study was to examine the factors that influence the completion of PhD degrees and identify obstacles to completion at a Hispanic Serving Institution. Low completion rates are a national and global problem predicted to generate a critical shortage of professionals needed by society. The researcher utilized a phenomenological qualitative study to research the phenomenon through the interpretation of an individual's experiences in various situations (Stake, 2010). This research is important as it aims to analyze programs with high completion rates to find the factors that contribute to or impede dissertation completion. This project will focus on doctoral program designs aimed at improving completion rates. Tinto's theoretical model of persistence is frequently utilized in research projects to examine student retention and attrition. Tinto (1975) emphasizes that student engagement in both the social and intellectual environments is crucial for completing a degree. This study examines the experiences, challenges, and support mechanisms encountered by doctoral students throughout their academic endeavors.
