# Contexts

Contexts are the "areas" in Moodle where roles can be assigned to people

They are arranged in a hierarchical fashion, with permissions inherited from "higher" to "lower" contexts.

1. System (the entire installation)
2. Front page (the "site course")
3. Course Categories
4. Course Sub-categories
5. Courses
6. Blocks and Activities
