Behaviour of "old" 4.0 learning progress:

Setting "Multiple Pass Scoring": Score the last pass

• Test not started: No entry
• First question opened: Icon/Text: Failed, Score 0%
• First question answered (correct, points enough for passing): Icon/Text: Completed, Score 66%
• No change after successfully finishing the pass. (100%)
• 2nd Pass, first question opened: Still Completed/Completed
• First question answered (incorrect, success possible): Icon/Text Failed, Score 33%
• Second question answered (correct): Icon/Text completed
• 3rd pass, like 2nd, but two times wrong answer: Icon/Text: Failed

Setting "Multiple Pass Scoring": Score the best pass

• Test not started: No entry
• First question opened: Icon/Text: Failed, Score 0%
• First question answered (correct, points enough for passing): Icon/Text: Completed, Score 66%
• No change after successfully finishing the pass. (100%)
• 2nd Pass, first question opened: Still Completed/Completed
• First question answered (incorrect, success possible): Still Completed/Completed

Due to this behaviour in 4.0 we do not have a "in progress" status. During the test the status is "failed" unless the score is enough to pass the test, which makes the learning progress status "completed".

Parameters

integer	object id
integer	user id
object	object (optional depends on object type)

Returns

integer status
