This study aims to examine the effect of being a foreign student on academic performance of upper elementary students at St. Therese School. A questionnaire was administered to 26 students to collect data on their demographics, including gender, age, parents' education and occupation, and family income. The results showed that most respondents were female, aged 12-13, with college-educated parents in white-collar jobs, and family incomes between 20,000-30,000 pesos. The study aims to determine if factors such as being a foreign student influence academic performance.
