 {{% alert title="Note" %}} If there are multiple training sets configured to start on the same day, the CHT will determine the order alphabetically based on the form ID. Subsequent training sets will only be displayed once the previous ones are either completed or no longer valid the next day the app is opened. {{% /alert %}}
 
+Training materials can also be accessed in the training page found in the auxiliary menu for users to revisit as needed. Completed training is displayed with a green checkmark. _Added in 4.15.0_.

 ## Completing
 
 Health workers read through each card one by one in a predefined sequence, tapping “Next” on each card. When they are finished reading all cards, they tap “Submit” on the last card. The training set is now considered complete and they can continue using their app. Completed training sets show up on the [main list]({{< relref "building/features/reports/#main-list" >}}) of the Reports tab and they won’t be asked to complete this set again. If there are additional training sets to complete, they will be shown the next day the app is opened.
