Students in the Alamance-Burlington School System will lose three school holidays to make up for the school year’s start being delayed because of the need to clean mold from many school buildings.

After surveying families and school system staff on the options, the Alamance-Burlington Board of Education voted Monday night to convert Oct. 30, Dec. 20 and Jan. 2 to full instructional days to meet the state requirement for a total of at least 1,025 instructional hours for the full school year. Another option would have been to make school days longer.
