If you are unable to Change the Years and Terms Start/End Date this is probably due to overlapping school years.

Overlapping School Years/Terms can create multiple issues in the System. The only Terms that can overlap are Athletics.

To Change the school years and terms navigate to:
  1. Core
  2. Hover over Settings and select School information
  3. Select Years and Terms
  4. Select the Year from the drop-down
  5. Click the Edit pencil icon to change the dates accordingly
Note: You must end the previous school year the day before the next school year. For example, if your current school year is set to end 7/1/20XX then the start of next school year should be 7/2/20XX.
