We investigate the mobility patterns of elementary students enrolled in Arizona’s traditional public school districts and charter schools. We address interdistrict and charter school mobility simultaneously. Most student movement is interdistrict or between school districts. In Arizona, interdistrict mobility has played a greater role in creating and sustaining the “educational market” than charter schools. There is also a substantial amount of student movement from charter schools to school districts. Regression analyses suggested that the relationship between demographic and achievement variables and the different types of student mobility differed across the two sectors. We also document regional differences in mobility patterns, which indicate that education markets vary considerably across and even within local contexts
