Introduction: Stress, is a part of the student experience enough evidence suggests that comparatively to other trainings nursing students experience high levels of stress, psychological morbidity, and depression (Zvauya, Oyebode, Day, Thomas, & Jones, 2017). Whereas, as brain plays the vital role in adaptation to the stress and make necessary changes in the behavioural and physiological responses to become resilient (McEwen, Gray, & Nasca, 2015). A study conducted by Al‐ Zayyat, and Al‐ Gamal (2014) illustrated that students suffered from high level of stress in the clinical setting and reported that common stressors among the students are independently caring to the patients, high expectations of teachers and clinical staff, and clinical assignments. Whereas, stress is important in the learning process as without stress the students are unable to realize the importance of time, schedules, evaluation criteria and study milestones. Objective of the study: The objective of this study is to determine the correlation between stress and competence among nursing student in Lahore, Pakistan. Methodology: Co relational study design is adopted to fulfill the research objectives. The study was conducted in the Private University from January, 2019 to May, 2019. Population of the study were nursing students and the sample size was 191. Two scales naming nursing competence and perceived stress scales were used to collect data. Results: The mean score of perceived stress was 2.1 on the scale (1= Never to 5= very often) which shows that students were usually having low levels of perceived stress. The students shared low competency values on the sub scales of serving as an example for other nurses, ethically oriented practice, general aptitude and nursing care in a team. There was negative moderate (r= -0.46, p=<.005) relationship between nursing competency and perceived stress among students. Conclusion: Stress is the hindering factor for learning whereas effective coping behavior can facilitate learning. Stress is related to poor nursing competence.
