RollCall is task-centered. It's designed to allow you to quickly process recurring tasks such as class registration and recording attendance. Many of the tasks are optional, depending upon how the particular business is operated. For example, you don't need to record exam results if Exams are not assigned to classes. 

Each of the Task windows organizes data to support the ways in which an item can be entered. For Registration, Students are associated with Classes, so you can Register all students for a particular class, or all classes for a particular Student. 

Task windows limit the information shown to match the restriction criteria set up for the item. So, for example, if a Class has an age restriction, students with either blank or ineligible birthdays will not be shown. For Attendance, only classes held on the day of the week for the entered date will be shown.

For each of Task window, entering the key criteria -registration date for Registration or a check mark for attendance- adds the new record to the database. If the value is blanked out, the record is deleted. Several of the task windows allow adding additional information, such as whether to send an invoice for registration fees (or record cash payment) when the record is added to the database. 

All Task windows support a quick print of the list with focus using the print button at the bottom of the list or the File->Print (or preview or export) function. This is handy in the case of Attendance or Registration 'events' where the computer may not be available. The data can be recorded manually, and then entered later.

The Registration process is also used to setup one-on-one sessions for coaching, private lessons or tutoring. When a student is registered for a class (and the global option for Tutoring is turned on), you can setup individual sessions for the student. Track goals and results for each session and optionally invoice for the instructor's time. The Student's and Instructor's schedule show registered classes, as well as tutoring sessions.
