Custom parameters (grader launch)

Responses selection parameters

deliveryIds

json-encoded string[]

None

Enter the ID of the delivery for which the responses needs to be scored. 

testTakerIds

json-encoded string[]

None

Enter the ID(s) of the test-takers for which the responses needs to be scored.

presentationOrder

item , delivery, or title

None

Defines the order in which the responses will be presented to the scorer. Depending on the provided values, the sorting criteria will be either:

• item

  • Item order in the QTI test first

  • Delivery order (as given in the deliveryIds parameter) second

• delivery

  • Delivery order (as given in the deliveryIds parameter) first

  • Item order in the QTI test second

• title

  • Item title order (as defined in Authoring of Test Item title parameter)

  • Delivery order (as given in the deliveryIds parameter) second

    

unscoredFirst

"true" or "false"
true or false

None

Designates that un-scored tasks should come first:

Value can be string (“true”, “false”) or boolean (true or false); both are accepted. Examples:

“unscoredFirst”: "\"true\""
“unscoredFirst”: "\"false\""
“unscoredFirst”: "true"
“unscoredFirst”: "false"

• If “true” or true value is used: un-scored tasks are returned first.

• If “false” or false value is used or this claim is not sent: keep the existing behavior.

Precedence of custom parameters ordering tasks:
When both presentationOrderand unscoredFirst parameters are present, then the unscoredFirstparameters have precedence, meaning that all un-scored tasks are presented first, followed by the scored tasks. The un-scored tasks and the scored tasks are internally sorted by the value provided in the presentationOrderparameter.
