First create a master gradebook that contains gradebooks from multiple teachers. To do so, start a new gradebook. When a window appears stating that the gradebook has no classes, click the Import button (or choose Import from the File menu). Under the Built-in Formats tab, select Combine Gradebooks and click Next. In the window that appears, select one of the gradebooks and click Open. In a matter of seconds, all classes in the other gradebook will be imported in the master gradebook. Continue using the Combine Gradebooks format until all gradebooks have been imported. Print reports. It is important that the students’ names or ID numbers are identical in all teachers’ gradebooks. Note: there is a 250 class limit for a gradebook which means that you can typically combine up to ten gradebooks.
