Certain Star Reading features only apply to students who are enrolled in a Star Reading class.
So, what makes a class a Star Reading class?
Adding courses, adding classes, assigning products to classes, assigning teachers to classes, and enrolling students in classes are all tasks that are done in Renaissance. Usually, these tasks are done by an administrator (by default, teachers cannot perform these tasks).
When you assign teachers to classes, you are allowed to choose which Renaissance programs are used by that class/teacher and the role of the teacher in that class. Selecting Star Reading as one of the programs makes the class a Star Reading class.
