The percentage of 1st through 12th graders who change schools out of all students in a school year. Students must have attended both schools for which they were registered for at least one day. Additionally, this indicator only identifies the share of students that change schools for any reasons and not the frequency, number of school switches, or change in residences in a school year. The percentage reflects the last home address available for the student who changed schools. This may or may not be the home address provided for the first school that they are registered to attend.
