The Enroll History Report shows each enrollment listed by the enrollment date (the date the student was put into the class in your database). This report counts each class a student is enrolled in; if a student is in 2 classes, he/she will be counted twice.
The report results will include: family location, enroll date, enroll type, class location, class (and category 1), session, student, billing contact email, drop date, and days in class.
