# ExtendTrainingPlan
<a name="API_ExtendTrainingPlan"></a>

Extends an existing training plan by purchasing an extension offering. This allows you to add additional compute capacity time to your training plan without creating a new plan or reconfiguring your workloads.

To find available extension offerings, use the ` [SearchTrainingPlanOfferings](https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_SearchTrainingPlanOfferings.html) ` API with the `TrainingPlanArn` parameter.

To view the history of extensions for a training plan, use the ` [DescribeTrainingPlanExtensionHistory](https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_DescribeTrainingPlanExtensionHistory.html) ` API.
