Ideally, a good education system should be able to develop the potential of students in a holistic and integrated manner. In many academic literature, there are several evidences proving that the elements of spirituality are fundamental to students personal development that could produce well-balanced students. Earlier researches have shown that those who are more religious or spiritual, and use their spirituality to cope with life, experience many benefits to their health and well-being. Interestingly, spirituality has been found to have a positive effect on academic performance of students because highly spiritual students are associated with high learning motivation. To see these reviews in action, this research was a case study designed to examine the impact of students spirituality in the academic performance among Grade 11 students in Lumban Senior High School. Students enrolled in Humanities and Social Sciences strand (HUMSS) were selected using purposive sampling technique to sample 50 students out of 157 as respondents of this action research. The views were sampled through a questionnaire. The questionnaire largely comprised of Likert-Type questions. The study revealed that spirituality served as a source of inspiration to focus on studies and hard work. The study also showed that, students viewed spirituality in religious terms and tightly knitted spirituality to religion. Recommendations made from the study was that, students who had spiritual inclinations should not see their spirituality as a sure way to success. Students could also learn the virtue of focus and hard work in spirituality and apply it to their advantage in academics.
