====== Access restrictions ======

"Restrictions" allow teachers to set conditions for accessing an activity or work material in a course room. \\
Such conditions or prerequisites can be:
  * A specific date or period of time
  * An assessment (grade, score, etc.) that must be achieved beforehand in the course or in another activity
  * The completion of a previous activity

==== Set up prerequisites for a work material or activity ====

Go to the configuration page of the work material or activity for which you want to restrict availability, i.e. link it to certain prerequisites. \\ 

//Switch the course page to editing mode: Button "Switch on editing" - and in the edit menu behind the material or activity select the item **Settings**.// \\

In the "Prerequisites" section at the bottom of the configuration page, click on the **Add prerequisite** button. \\
A window opens in which you can click on different types of prerequisites to restrict availability.

**Date** \\
With this criterion you specify that the work material or activity is available from and/or until a certain point in time (date / time).

**Assessment**\\
With this criterion you set a condition for a certain assessment in the course: This can be a condition on the overall assessment in the course or on the assessment of an individual activity. You can specify a certain minimum or maximum score (expressed as a percentage), or both, or neither. You can create multiple assessment criteria (more on [[https://docs.moodle.org/311/en/Restrict_access_settings#Grade|moodle.org]]).

**Groups and Groupings**\\
You can restrict the visibility of the work material or activity to a specific group or grouping. \\
//This button only appears if there are groups or groupings in the course. See [[en/moodle/user/groups/start#group_access_for_activities_or_material|group access for activities or material]].//
