DRIFT happens, sometimes: Examining time based rater variance in a high-stakes OSCE

Karen Coetzee & Dr. Sandra Monteiro

BACKGROUND

  • To what extent does DRIFT exist in 12 stations of the high-stakes IENCAP OSCE in which nurse examiners are subjected to a highly rigorous two-phase training process?
  • Differential rater function over time (DRIFT) is described as increasing leniency in standardized assessments due to rater fatigue over time1.
  • Internationally Educated Nurses Competency Assessment Program (IENCAP) is a high-stakes assessment conducted at Touchstone Institute in collaboration with the College of Nurses of Ontario (CNO).
