The COVID-19 Transfer, Mobility, and Progress report series aims to identify the ways in which the pandemic is changing transfer pathways across higher education. The pandemic's impacts on transfer enrollment shifted as the pandemic progressed, with transfer pathways and student groups showing diverging patterns over time. As the ninth issue in the series, this report summarizes notable changes in transfer enrollment and persistence post-transfer over a two-year period, with results broken out by academic year, student characteristics, and institution type and selectivity. In addition to the minority-serving institutions analyzed in previous editions, such as Historically Black Colleges and Universities (HBCUs) and Hispanic-Serving Institutions (HSIs), this report offers a new analysis of Rural-Serving Institutions (RSIs) to gain insight to how transfer pathways were impacted in rural communities over the last two years. The analysis of RSIs unpacks the broad category of four-year institutions to provide deeper understanding of the sharp decline in upward transfers and the stabilization in lateral transfers between four-year institutions--two notable trends in the second year of the pandemic. The findings in this report are based on a fixed panel of institutions representing 89.9 percent of the Clearinghouse universe of institutions, where over 13 million undergraduate students were enrolled, including 2 million transfer students, during the 2021-22 academic year as of June, 2022. Throughout the report, "pandemic year 1" refers to academic year 2020-21 and "pandemic year 2" refers to academic year 2021-22 whereas academic year 2019-20 is referred to as "pre-pandemic year."
