The STEM Transfer Partnership (STP) initiative seeks to create systemic change within STEM degree pathways in Washington through collaboration between teams of faculty and staff from nine pairs of two-year and four-year institutions across the state. These teams are supported by Community College Research Initiatives (CCRI) to work together to improve STEM transfer processes by serving as institutional context experts and determining the focus of their efforts (see Cate et al., 2022 for more details). STP teams have worked within institutional pairs for eighteen months to understand and dismantle obstacles to low-income STEM transfer students' bachelor's degree completion. This brief examines into the factors propelling their change and also highlights the tangible strides made by STP teams in their pursuit of fostering positive transformations.
