Maryland Student Mobility (SY 2003-2024)

Student mobility data from the Maryland State Department of Education (MSDE). The original CSV data files downloaded from MSDE are available in the data-raw/extdata folder on the GitHub repo for the package. Mobility refers to the movement of students from one school to another during the school year. Three types of mobility are calculated using student entrants and student withdrawals: Total student mobility, entry mobility, and exit mobility. Student mobility is the percentage of students that either enter or withdraw from a school during the school year. To calculate student mobility, the number of entrants is added to the number of withdrawals and that sum is divided by the average daily student enrollment.
