This study investigates the impact of a STEM-focussed International Women’s Day event which was attended by over 80 students 14–15-year-olds students over two years. This event comprised of an introduction session on the history of feminist, where we started and where we are now in term of gender equality in STEM (through an intersectional lens). The students then undertook a series of hand on STEM workshops and a panel discussion with current STEM degree students. Pre- and post-event questionnaires were utilised to determine students views of various STEM subjects, their interest in STEM careers and their feelings towards equity in STEM before the event and the resulting impact on the event. The event was primarily attended by female students. The findings reveal a shift in students' views of equity in STEM, when asked “What are your feelings about the current state of the STEM field relating to inclusivity” at the start of the day 43% stated “Hopeful”, this increased to 59% at the end of the day. Students’ interest in STEM subjects also increased, with 51% of students being more interested in Biology after the day, 33% of students being more interested in working/further education in Chemistry after the sessions and 36% of students being more interested in working/further education in Engineering after the sessions. The results suggest that well-structured outreach programs can positively impact female students’ aspirations and perceptions, a key element in addressing gender disparities in STEM education and subsequently the workforce.
