States and districts are asked to not create or change rosters until Monday, March 13 at 8:00 a.m. Central time.
During this time, ATS is proactively reviewing rosters for all states, and removing courses where courses are included.
After Monday at 8:00 a.m. states and districts are encouraged to check rosters and correct subjects if necessary. To correct a subject on a roster, create a new roster and move the students to the new roster. The old roster will automatically be deleted after removing the last student.
For more information see the Test Update from March 2 and the Data Management Manual (sections titled Change Roster Data and Manage Roster Data).
