2020-21 School Year

  • For the 2020-21 school year, Lewisville ISD extended the school day by 25 minutes each day to help us “bank” minutes. By "banking" minutes, if the need arises to close for a period of time, the district ideally would not have to add days to the end of the school year. The hours below reflect the 25 minutes added to the school day.
