ABSTRACT
Student mobility is an increasing problem now recognized as a detriment to student learning. Mobility is defined as a measure of the number of times a student changes schools, excluding changes due to single grade-level promotions (U.S. Department of Education, National Center for Education Statistics, 1995). Mobility has not always been pinpointed as a cause of poor achievement because it is frequently found in combination with other atrisk characteristics such as poverty, limited English proficiency, substandard health and living conditions, and changes in family structure. However, not only mobile students, but also nonmobile students, teachers, schools, and entire districts also suffer the impact of mobility.
