How to Improve My Inspection Accuracy?
Data Source: MCMIS inspection records for 12 months representing interstate carriers and intrastate carriers transporting hazardous material, and includes large trucks and buses.

The Inspection Accuracy measure evaluates 12 months of data to determine your State’s rating. A record is evaluated if the date of the initial upload falls within that 12-month range. As shown below, the range begins 15 months before the evaluation month, but excludes the most recent three months of records. These records were used to calculate the leading indicator, which forecasts where measures may be trending.

 

In the example, the January 2019 evaluation looks at the 12-month event date range November 1, 2017, through October 31, 2018. Inspections that occurred after October 31, 2018, were used to calculate the leading indicator.

evaluation period

This measure evaluates inspection records representing interstate carriers and intrastate carriers that carry hazardous materials, and includes large trucks and buses. It analyzes the inspection records with carrier information that matched to a carrier in the Motor Carrier Management Information System (MCMIS).

 

The percentage of matched records is determined by dividing the number of matched records by the number of total records evaluated. If the percentage of matched records is

  • 95% or more, the rating is GOOD
  • Between 85% and 94%, the rating is FAIR
  • Less than 85%, the rating is POOR
