Aptem retrieves all learner records from the LRS and applies a de-duplication process. However, it does not control the order in which records are returned by the LRS. This means that, on occasion, an older record may overwrite a more recent one, and only one record will be displayed in Aptem. As a result, if a qualification has been attempted twice, it will only appear once in Aptem.
FAQ: Why do some learners' qualifications appear on their PLR within the LRS but not on their PLR in Aptem?
