“Restriction by week from start“ is a new availability type plugin released in the Moodle plugins database recently which allows you to release course activities or sections with a relative week shift from course start date.
The simple and yet very useful plugin developed by Valery Fremaux is focused on doing a small improvement perfectly and is a must have plugin. However as of now the plugin is only available for Moodle 2.7 version.
The plugin provides you the capability to put a new access restriction condition for any course section or any course activity. The restriction capability allows you to release the course content after a certain weeks have elapsed from the course start week otherwise it will be hidden from the students.
The current version of the plugin however supports only setting 6 weeks shift from the course start date but as per the plugin developer it can be extended to more weeks in the next release.
You can download the plugin from the Moodle plugins database here and make sure to test it out on a development server before using it on the production server. The plugin is also awarded with theAutomated Testing Support Badge.
