Students or parents encounter the message for a course on their portal, while assignments are submitted and should be graded already:
No Grades Published
This message is displayed for the courses for which teachers have not yet published any grades for the current term.
If assignments were already submitted by you, as a student, you can reach out to the corresponding teacher and ask them to publish the grades.
After the grades are published by the teacher, they are visible on the main page of your portal once you log in to School Loop.
