score-without-statusThe course sent a score but never said whether the learner passed, so the LMS has to guess.
Reports show a score against an attempt that is still incomplete, or a passing score recorded as a fail. Different systems resolve it differently, so the same package behaves inconsistently across LMSs.
Writes to cmi.core.score.* (1.2) or cmi.score.* (2004) with no accompanying status write in the same session.
A score is a number; the status is the judgement. SCORM does not require an LMS to derive one from the other. Some apply the mastery score, some leave the attempt open, and some mark it complete but unpassed — which is why this shows up as an inconsistency between systems rather than as an outright failure.
Whenever the course sets a score it should also set the outcome. In 2004 that is cmi.success_status for pass or fail and cmi.completion_status for whether the content was finished; the two are deliberately separate. In 1.2 the single cmi.core.lesson_status carries both.
Open a package in SCORM Lab to see whether this applies to yours. It runs in your browser, and nothing is uploaded unless you choose to share it.
Stuck on this one, or seeing it only in a particular LMS? That is usually a short conversation — scormspecialist.co.uk.
