This descriptive study determined the predictors of research performance of the graduate students in Occidental Mindoro State College, San Jose, Occidental Mindoro, Philippines. This research specifically looked into the graduate students' level of research performance, attitude towards research, challenges encountered, and the strategies employed to cope with the research challenges. A total of 41 completely enumerated students enrolled in Methods of Research and Thesis Writing during the second semester of Academic Year 2018-2019 served as respondents of the study. The study found that the graduate students' level of research performance is high, specifically in writing the statement of the problem, hypothesis, significance of the study, and definition of terms. They have a positive attitude towards research in terms of usefulness and predispositions. They have negative research anxiety. Challenges encountered include insufficient funds, developing interest, inability to select researchable topics, and limited related literature. Coping strategies employed were frequent consultations with the adviser, seeking help from other competent faculty and students, using technology, and giving material appreciation. Attitude and challenges encountered were found to be predictors of the graduate student's research performance. A positive attitude towards research and the moderate challenges encountered could affect the graduate student's research performance.
