# Customize Checksum Validation

During post-processing, Eduction attempts to validate a match by calculating a checksum. If 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 applies a score penalty, and add an `INVALID_CHECKSUM` component to the match.

NOTE: This environment variable has the same name in all grammar sets. That is, it is `IDOL_PII_CHECKSUM_VALIDATION_STRICT` for the PII, PHI, PCI, and GOV grammar post-processing script.

You can configure the score penalty by setting the environment variable `IDOL_PII_CHECKSUM_VALIDATION_FAIL_PENALTY` to a value between 0.0 and 1.0. When validation fails, Eduction multiplies the score by this value. The default value is 0.9.
