<p>An introvert is said to be a kind of student who is quiet and doesn’t open easily. On the contrary, when a student is friendly, talkative and quickly makes friends, the student’s form of personality is extroverted. This study aimed to know the difference between the self-confidence of introvert students and extrovert students. Introverts and extroverts pick their preferences from different priorities. For them to enhance their confidence students should establish a strong belief for their selves. The development of self-confidence must be essential and allows students to demonstrate their expertise and talents. The study was a quantitative design that makes use of the research questionnaire. The researcher surveyed the Senior High School with a total of two hundred thirty-five respondents who are requested to answer the questionnaire. Quantitative data were processed using chi-square. The study has shown the students' self-confidence in terms of education, talents, socialization, and achievements. It shows that introvert students have a higher frequency than the extrovert students. Results also show that self-confidence implies that the extrovert respondents are not enough in expressing their personality. They need to re-build their personality types to gain some confidence. It can be inferred that there is no significant difference between the self-confidence of the introvert students and extrovert students.</p>
