Indianapolis Public Schools has changed graduation ceremony dates for five of the district’s high schools, raising complaints from family members who have already made travel plans for out-of-state relatives. Superintendent Eugene White said the district was forced to move the graduations because tough winter conditions added four makeup days to the schedule. Parents say more than a month’s notice about the changes should have been provided. White said he waited to change the dates because he hoped the state would waive its 180-day school-year requirement, but he didn’t apply for the waiver until April 13. The state rejected the request.
