# Customize Checksum Validation

During post-processing, if an Eduction match can be validated by calculating a checksum and validation fails, the match is discarded. You can customize this behavior by setting environment variables that are read by the post-processing script.

To stop rejecting Eduction matches that fail checksum validation, set the environment variable `IDOL_PII_CHECKSUM_VALIDATION_STRICT` to `FALSE`. Instead, the script will apply a score penalty, and add an `INVALID_CHECKSUM` component to the match.

You can configure the score penalty by setting the environment variable `IDOL_PII_CHECKSUM_VALIDATION_FAIL_PENALTY`. This specifies a value by which the score is multiplied when checksum validation fails. Choose a value between 0.0 and 1.0. The default value is 0.9.
