Work Comp Schedule Ratings Backed by FSU Research
Some of the Work Comp Schedule Ratings produced by NCCI, WCIRB, and other rating bureaus now have science to back the Schedule Debits or Credits. The definition of Schedule Ratings can be found here.

A recent study by Florida State University has shown that a dull and dirty work areas affect cognitive function. One of the researches had commented- “Designing jobs to ensure that all workers have some decision-making ability may protect cognitive function later in life, but it’s also about cleaning up the workplace.”
The Schedule Ratings take into account that dirty and unkempt workplaces can cause workers to not pay attention to their jobs. When the workers stop paying attention, accidents will occur at a much higher rate than a normal workplace.
