Federal regulators met this January 15, 2019 in Washington.  CSA and the new IRT (Item Response Theory) model were discussed.

In 2019, the agency plans to continue its second year of study on a new method to improve the Compliance, Safety, Accountability Safety Measurement System using what is known as the Item Response Theory model recommended in a 2017 study by the National Academy of Sciences.

The new CSA model, expected to take at least two years before implementation, is expected to use data for informed policy decisions that are currently largely based on expert judgment, said Joe DeLorenzo, director of FMCSA’s office of enforcement and compliance.

“The model can see things not apparent to our expert judgment,” DeLorenzo told an audience of about 200. “The general construct will likely remain the same but the BASICs may change.”

DeLorenzo said the agency plans to conduct a small-scale data test in the next few months using the IRT model.

(BASICs are the agency’s seven Behavior Analysis and Safety Improvement Categories used to compile CSA scores.)
