Use the Register Usage Codes reference data to manage the values that are used by staff to mark registers. There are three different mark types that hold usage codes:

• Learner
• Staff
• Room

The Learner mark type differs slightly from that of the Room and Staff types.

Room and Staff mark types are the same except they do not have a Positive Attendance or a Positive for EMA fields but are not relevant to users of Ontrack Staff Hub.

The fields on the Register Usage Codes screen for learners are described in the following table.
