Question - How can I report on Travellers' attendance?
Answer - You can set up a dynamic group for your travellers, in Reporting > Data Digger. Select Travellers from the dropdown, the select each subtype to note the numbers recoded in each type. Save as separate dynamic groups, or make a note of the names and set up a Static Group that incorporates all Traveller students. Use this group in the % Attendance Between Report (Reporting > Reports > % Attendance Between).
