# Assign training to hierarchy level

<Warning>
  Only users with the <b>ADMINISTRATOR</b> scope in the current context can assign trainings to hierarchy levels. Make sure your API token grants administrator privileges.
  See [Understanding Scopes](/OpignoEnterpriseAPI/UserContextManagement#understanding-scopes) for more information.
</Warning>

To assign a training to a specific hierarchy level, use the `assignTrainingToLevel` mutation.

**Access policy:**

* The API user context must have permission to manage training assignments.
* The specified `trainingId` must exist and be accessible.
* The specified `hierarchyLevelId` must exist and be accessible.

The mutation accepts the following arguments:

| Argument           | Type | Description                                                                       | Default |
| :----------------- | :--- | :-------------------------------------------------------------------------------- | :------ |
| `trainingId`       | `ID` | Required. The unique identifier of the training to assign.                        | —       |
| `hierarchyLevelId` | `ID` | Required. The unique identifier of the hierarchy level to assign the training to. | —       |

<Note>
  This operation creates a relationship between a training and a hierarchy level, making the training available to users assigned to that level.
