This paper explores tools for understanding student transitions and mobility. Student transitions and mobility together form what could be termed student pathways, or the lines of movement that students follow while in school . either in elementary, secondary, or postsecondary education (PSE). Knowing how students progress between and move within education systems is invaluable to the management and continued improvement of education systems. More specifically, the ability to view student transitions and mobility through observation of individual student-level activities over time can help the education sector better plan, as well as isolate factors that contribute to specific educational outcomes for specific groups of students.
