In Flexible Classroom, the teacher can click **Leave Classroom** to temporarily exit the session without changing the room status. To officially end the class, follow these steps:

1. The teacher calls the `leaveClassroom` method to exit the classroom:

   ```javascript
   this.classroomStore.connectionStore.leaveClassroom(LeaveReason.leave);
   ```

   The `ClassState` reflects the following states:

   ```javascript
   ClassState {
       beforeClass: 0, // Class has not started
       ongoing: 1,     // Class is ongoing
       afterClass: 2,  // Class has ended, but the classroom still exists
       close: 3        // Classroom is closed
   }
   ```

2. To actively end the room, call the room status update interface `RoomStore:updateClassState`:

   ```javascript
   // End the room
   this.classroomStore.roomStore.updateClassState(ClassState.close);
   ```

3. To end the course without direct interaction, call Flexible Classroom backend RESTful interface [Set Classroom Status](/en/api-reference/api-ref/flexible-classroom/classroom-rest-api?platform=android#set-the-classroom-state). Set the class status to one of the following values:

   * `0`: Not started
   * `1`: In progress
   * `2`: Ended. The class time has elapsed, but users can join and remain during the extended time.
   * `3`: Closed. The class is closed after the extended time, and all users are removed and cannot rejoin.
