To create a custom role:

1. Go to Settings > Site administration > Users > Permissions > Define roles.
2. Click the "Add a new role" button.
3. Give the role a Short name e.g. 'Parent'. The short name is necessary for other plugins in Moodle that may need to refer to the role (e.g. when uploading users from a file or setting enrolments via an enrolment plugin).
4. You must provide a full name for all custom roles. If you need to name the role for multiple languages you can use multi-lang syntax if you wish.
5. Give the role a description (optional).
6. Select an appropriate role archetype (see below for further information).
7. Select the contexts where the role may be assigned e.g. 'User' for Parent role.
8. Set permissions as required.
9. Scroll to the top or bottom of the page and click the "Create this role" button.
10. As an administrator, go to Settings > Site administration > Users > Permissions > Define roles and click the "Add a new role" button.
11. Give the role a name (such as "Parent", but it can be anything appropriate, such as tutor/mentor) and assign it to the user context.
12. Under the heading of Course
13. Change moodle/user:viewdetails to allow - to access the student's profile

Assigning the parent to the student

• Go to 'Profile settings for [username]' > 'Roles' >'Assign roles relative to this user'
• Choose the role to assign i.e. Parent
• Select the parent in the potential users list and use the Add button to add it to the existing users list.

Adding the Mentees Block

This block needs to be added so parents can see links to their child's profile.

• On the Front Page, turn editing on.
• Go to the Add Blocks block and select the Mentees block and when it appears, click on the Configuration icon.
• Edit the configuration settings to suit the needs of the site. When complete, save the changes and return to the Front Page.

How a parent sees their child's activities

• Once the mentees block has been added, a parent/mentor sees the link to any children/mentees they are responsible for.
• They click on a name and will be taken to the profile page of that user.
• They then click -next to "Course profiles" - the name of a course the user is enrolled in.
• Grades may then be viewed by clicking in the user's profile "Activity reports>Grades"
• Forum posts may also be viewed from the user's profile.
