School officials in Des Moines have reversed a decision to hold classes on Martin Luther King Jr. Day.
The Des Moines school district unanimously voted Thursday to cancel its plans to hold classes on Jan. 21. Officials had previously announced that students would attend classes on the holiday to make up a snow day.
The Des Moines Register reports a local NAACP youth group criticized the district's move and collected hundreds of signatures for a petition against the decision.
Another snow day was scheduled for Presidents Day in February. The district now plans to make up the snow days in June.
