About Exam Scores

  • The raw passing score is mathematically transformed so that the passing scaled score equals 650. The scaling process is similar to the adjustment for Celsius and Fahrenheit temperature scales. While the values may differ, the temperatures are the same (e.g., water boils at the same temperature regardless of the scale used).
  • A scaled score is not a percentage score but a transformation of a raw score. Scaling is done to report comparable results when forms and raw passing scores vary over time.
