University-led science, technology, engineering and mathematics (STEM) outreach plays an important role in addressing declining rates of student participation in tertiary STEM programs and declining interest in pursuing careers in STEM fields (Sadler, Eilam, Bigger & Barry, 2018). One type of outreach program that is becoming more popular is the school-university partnership. This is often a formal arrangement between a university and a single school or a group of schools. Partnerships to support innovation in school science and mathematics are a key strategy of successful STEM countries (Marginson, Tytler, Freeman & Roberts, 2013). This article reports on a school-university partnership program, known as the Wanago program, located at the University of Technology Sydney (UTS) that allows secondary school students to pursue STEM subjects on the university's campus. The impact of the program in STEM studies for secondary school students, personnel and resources that supported student learning, and how participation in the program supported leaning outcomes for the students are explored.
