Investigating the gender gaps in mathematics scores is used by maths educators and researchers to gain a deeper understanding of students’ performances. This exploratory study analyses scores in mathematics courses offered in the National University of Samoa Foundation programs. Using statistical tests to understand the nature and extent of the gender gaps in performances, the results show that while females dominate enrolment numbers, overall performance in terms of marks is dominated by males. The study concludes that more research is needed and critical in unearthing relevant evidence to inform policy and strategies to support maths learning of both male and female students.
