title: Interrater reliability of Western University's on-road assessment.
abstract: BACKGROUND
  Little empirical support exists for interrater reliability between evaluators from different backgrounds when assessing on-road outcomes of drivers.
  
  
  OBJECTIVE
  We quantified interrater reliability of on-road outcomes between a certified driving school instructor (DI) and an occupational therapist and certified driver rehabilitation specialist (CDRS).
  
  
  METHODS
  Both raters used the Global Rating Score (GRS) with two levels (pass, fail), the GRS with four levels (pass, pass with recommendations, fail remediable, fail), and the priority error rating score (PERS; most frequently occurring on-road errors in priority order) to assess 35 drivers (age, M = 48.31 years, SD = 9.76 years; 40% male; 86% with multiple sclerosis).
  
  
  RESULTS
  The DI and occupational therapist CDRS had excellent agreement on the GRS with two levels (κ = .892, p < .0001), GRS with four levels (κ = .952, p < .0001), and the PERS (κ = .847-.902, p < .0001), indicating interrater reliability.
  
  
  CONCLUSIONS
  This research contributes to empirical support for the on-road assessment.
