QAR Headline Report from the Quality Dashboard does not include all learners because QAR calculations are based on planned end dates within the funding year. However, there is another tab named 'Learner Data Table' in the quality dashboard, which doesn't have any filters applied to it, so it displays all ILR aims for the hybrid end years greater than 2018/19.
The benefit of having this export is that you can review any potential discrepancies observed within the QAR summary table and verify the hybrid end year of the learners in question.
