# activeContext

The currently active context.

## Declaration

```swift
var activeContext: CLSContext? { get }
```

## Discussion

Discussion This value is nil if there is no currently active context. To activate a context when a student begins working on the content that the context represents, call its becomeActive() method. To deactivate a context when the student finishes, call its resignActive() function. Only one context may be active at a time. If you activate a context, the system automatically causes any previously active context to resign.
