Teachers personality plays a significant role in accomplishing students educational achievement. Teaching and learning have a major part in creating a friendly and encouraging learning environment for students. In this context, the current research was conducted to explore the influence of tutors character on pupils learning and accomplishment. It was a descriptive correlative research approach. The sample comprised of 1,152 teachers and 2,304 students of 10th grade of public and private secondary schools who were chosen through a cluster sampling technique. The respondents were taken from 12 districts of Punjab, Pakistan. Two questionnaires; one for teachers and one for students were used to collect data. Teachers questionnaires were based on an adapted personality measure scale of John and Srivastavas Big Five Inventory (1999). The statistical analysis displayed no significant rapport among teachers personality and pupils academic success. The regression analysis and correlation coefficient showed that the dimension of agreeableness, extroversion, neuroticism, and conscientiousness has no correlation with students performance. However, openness has a significant correlation between students performance.
