Attendance schemes provide the criteria for marking attendance in a register. Each attendance register uses one attendance scheme, which you assign when creating a new register. The register defines the applicable users and sessions, and the attendance scheme defines the attendance statuses that you can give to users for each session.
For example, a simple attendance scheme defines two possible attendance statuses: present and absent. If you apply this scheme to an attendance register, you have two options for marking attendance for the register’s sessions. Mark users that attend a session as present and users that do not attend as absent.
You can create more complex schemes that define more statuses such as late and authorized absent. This provides flexibility to accommodate a wide range of attendance options.
