What is Score Standardization?
Score standardization is the process of converting an assessment score to a common metric while considering how applicants performed relative to each other.
Calculating a standardized score includes finding the average score and determining how spread out the
applicant scores are from the average.
Why Standardize Scores?
Standardizing is a best practice when comparing or combining scores on two or more assessments, such as a USA Hire assessment with a second assessment that measures technical competencies when both are used for determining an applicants final rating.
Before comparing/combining two or more scores that are based on different scoring scales (e.g., 0 – 50 and 0 – 200), we first want to make the scales more equal in meaning. This involves more than simply putting the scores on the same scale, i.e., transmuting them to the 70 – 100 scale.
We also need to consider how the scores are distributed. In other words, what is the average score? How spread apart are the scores?
