The Data Quality module identifies FMCSA resources for evaluating, monitoring, and improving the quality of data submitted by States to the Motor Carrier Management Information System (MCMIS).

SSDQ Evaluation Adjusted
The Non-Fatal Crash Completeness (NFCC) measure was removed from the Data Quality methodology. However, the evaluation will continue to be available as an improvement tool to help States evaluate the completeness of reporting non-fatal crash records. Visit the Continuous Improvement area for more details.

FARS/MCMIS Matching Tool Updated
The FARS record set now contains records from the FARS’ Parkwork data set, which includes information about parked and working vehicles involved in fatal crashes. Visit the Matching Tool Description area for more details.
