What will be an ideal response?

Standardization is crucial for effective measurement because it increases accuracy, improves comparability of scores, increases reliability, reduces contamination error, and enhances validity. Standardization is the consistent administration and use of a measure. It reflects the consistency and uniformity of the conditions as well as the procedures for administering an assessment method. Computerization helps to ensure that all respondents receive the same instructions and the same amount of time to complete the assessment. Standardization increases the fairness of the assessment system. Because maintaining standardized conditions is the responsibility of the people administering the assessment, training all administrators in proper procedures and control of conditions is critical. This is true for interviewing as well as any other assessment approach. In addition to being legally important, standardization is also valuable because recruiters should consistently evaluate candidates on their competencies, styles, and traits.
