Large numbers of students were absent from Grand Rapids Public Schools today.
Officials with the school district believe this was because of the nationwide "Day Without Immigrants" protest.
So many students were absent that the district might not be able to count this as an instructional day. School administrators may have to add an extra school day to the calendar.
John Helmholdt, a spokesperson for the school district, said no students will be punished for missing school due to the protest.
