When you select the Preserve existing completions option, any existing course completions are marked to permanently maintain their status of COMPLETE once your Skillport database is re-summarized.
You should select this option if you intend to change the completion criteria of courses (for example, by raising or lowering the minimum test score), but you do not want the changes to impact users who have already completed affected courses based on the old criteria.
Preserving existing completions is a permanent action; if you later disable the option (by clearing the check box), all completions that have been frozen are still marked as COMPLETE.
If you do not freeze existing completions, when Skillsoft Technical Support re-summarizes your database, all existing completions are reevaluated based on the new criteria. This can result in the completion status changing from COMPLETE to STARTED for some learners.
Example
Consider the following scenario:
You set the company-wide completion criteria as follows:
Learner A ends a course session for Course X, and a score of 80 is reported to Skillport. The course is marked as COMPLETE based on the defined criteria.
You change the value for Minimum test score to 85 and have Skillsoft Technical Support re-summarize your database.
When the database is re-summarized, the completion status for Course X is reevaluated based on the new criteria. Learner A's score does not meet the minimum test score, so her course completion status is changed to STARTED.
You change the value for Minimum test score back to 75 and have Skillsoft Technical Support re-summarize your database.
When the database is re-summarized, the completion status for Course X is reevaluated based on the new criteria. Learner A's score exceeds the minimum test score, so her course completion status is changed to COMPLETE.
You select Preserve existing completions, click Save, and have Skillsoft Technical Support re-summarize your database.
When the database is re-summarized, Learner A's completion of the course is frozen, that is, it is permanently marked as COMPLETE.
You change the value for Minimum test score to 90 and have Skillsoft Technical Support re-summarize your database.
When the database is re-summarized, even though Learner A's score does not meet the new completion criteria, her completion status remains unchanged because her completion for Course X has been frozen.
