If I go to batch transfer, I can see a option called "Graduation". What is this for?

The particular user can graduate the students if they have completed their studies in the institution. After a batch is graduated, all students of the particular batch will be moved from the active list of students to the Former/Alumni list. The administrator or a privileged employee (Manage Course/Batch privilege must be provided) can graduate a batch of students. 

       

There are also options to uncheck the students who are not eligible for graduation, status field to enter the comment, Leaving date field is provided to mark the leaving date of the students and an option to generate TC.

       

The generated certificate would look like :-
