Evaluator Calibration

The National Dental Assisting Examining Board ensures that clinical evaluators receive standardized training through a process known as calibration. Calibration occurs prior to every Clinical Practice Evaluation session.

The purpose of Calibration is to determine the amount of deviation from the standard that will still be considered acceptable. Calibration is designed to improve inter-rater reliability which is defined as "the ability for multiple evaluators to understand and apply a set of criterion in the same way" (ADEA Washington, DC, 2000)

Why Calibration?

  • Reduces examiner subjectivity, bias and individual interpretation in high stakes examinations
  • Improves inter-rater reliability by developing consensus in the application of criteria
  • Provides critical analysis of the evaluation instrument, ensuring reliability and validity
