This showcase highlights how a university in northern Japan integrates the IVEProject, a large-scale virtual exchange that hosts two eight-week sessions annually, involving over 5,000 students from 20 countries in its most recent October–November 2025 exchange. Initially introduced in select classes in 2017, the project has been implemented across all first-year Communication courses, encompassing approximately 250 students taught by four instructors, since 2020. While a range of students exist in these courses, the average student possesses CEFR A2 levels of English and has little to no prior experience using English to communicate with international peers. As the IVEProject has evolved, the instructor’s assessment strategies have adapted to better leverage the affordances offered while also accommodating the constraints of limited instructor time. This presentation explores how the instructors provide balanced, data-informed feedback to students each week. It also addresses challenges such as students attempting to “game” the system by submitting duplicate posts, as well as presents how assessment is designed to foster meaningful discussions and deepen engagement with international peers. The session concludes with an open discussion, inviting participants to share their diverse perspectives on assessment in virtual exchange.
