Student mobility is a widespread phenomenon in Houston area public schools (Potter et al. 2020), which often has negative consequences for students’ performance and attainment (Gasper, DeLuca, and Estacion 2012; Hanushek, Kain, and Rivkin 2004; Rumberger 2003; Stroub and Gill 2021). While being widespread, student mobility is not uniform across all campuses (Welsh 2017). This brief builds on earlier research looking at what predicted whether a student would change schools during a school year (Gill 2021) to focus on what predicts the amount of student mobility taking place at a campus. As such, this brief relays findings from analyses exploring how campuses’ student body characteristics, neighborhood features, campus attributes, and nearby alternative schooling options influence campus mobility rates.
