Backfill Process Definition

DEFINITION

1. Where a provider's data is missing from a freeze (a snapshot of a database), under certain circumstances the missing data can be copied from previous returns to provide a more accurate picture of the data for analysis. This process is called backfilling.

DETAILED DESCRIPTION

2. Backfill is usually only used for National level enquiries where the missing provider returns could be of large enough significance to corrupt the analysis result.

3. Backfilling is only done for Learner Responsive returns, specifically for F01, F04 and F05.
