What does standardization mean in measurement?

• A. The use of flexible approaches in test administration.
• B. The implementation of random methods to enhance testing variability.
• C. The use of systematic methods and established norms as reference points.
• D. The application of personalized assessments based on individual needs.

Answer: (C)

Standardization in measurement refers to the use of systematic methods and established norms as reference points to ensure consistency and comparability in test administration and scoring. This means that standardized tests are designed so that all test-takers experience the same conditions, instructions, and scoring processes. This is crucial for obtaining reliable and valid results that can be compared across different individuals or groups. The establishment of norms allows stakeholders to understand how an individual's performance compares to a larger population, which can inform decisions about education, employment, or treatment. Without standardization, it would be difficult to determine how a test-taker's performance aligns with or deviates from established benchmarks, undermining the test’s purpose and utility. Thus, standardization plays a vital role in the credibility and effectiveness of assessments.
