Borrower restrictions are assigned to tutor groups via the tutor group's record card.
Log into your library site and load Management, then select 'Tutor Groups' in the left-hand menu.
Select the required Group you wish to assign and click 'Edit' in the right-hand menu.
In the 'Restrictions' box, you will see the restriction group assigned to this Tutor Group. If it has not been changed, this will be the default as set in the borrower restriction settings. You can replace this with a custom created group which will then be applied to all borrowers in this group instead of the default.
Please note that this will not affect any borrowers that have had their restriction changed on their individual record card.
