The Instructional Support System displays data that is delivered to us by the individual districts. Seeing the wrong roster of students indicates there is a problem with the data that the district is sending to us. If you are in the high school or middle school please contact the guidance office and let them know that your rosters are incorrect in the ISS. If you are in an elementary school please contact your principal. They will need to work with your data manager to correct the data that they are sending us. Once the data is corrected, you should see the correct rosters the next day.
