Item Response Theory (IRT)

Section 5221 of the Fixing America’s Surface Transportation ACE (FAST Act) required the National Academy of Sciences (NAS) to conduct a study of the Compliance Safety Accountability (CSA) program and its SMS. On June 27, 2017, the NASEM panel issued a report titled “Improving Motor Carrier Safety Measurement,” which argues for FMCSA to adopt a more statistically principled approach. In response to the NASEM recommendation and the corresponding corrective action plan, FMCSA initiated a Correlation Study, a multi-year effort focused on developing and evaluating an IRT model to determine if the statistical rigor and complexity of IRT yields sufficient benefits compared to SMS to be integrated into the Agency’s prioritization process.
