What is meant by standardization in testing?

• A. Researchers provide the protocol to administer and score the exam, ensuring the test is given and scored the same way at each administration
• B. The process of verifying test security
• C. The method of calculating grades
• D. The process of translating items into other languages

Answer: (C)

Standardization means using a single, uniform protocol for how the test is given and how it is scored so every administration follows the same procedures. This includes providing the same directions, the same timing, the same materials, and trained scorers using the same scoring rules and answer key. When these steps are consistent, scores are comparable across different test takers and testing occasions because differences in results are more likely due to actual ability rather than variations in administration. The other options touch on related ideas but aren’t the definition of standardization: protecting test security deals with preventing cheating and leakage of items; calculating grades is about turning raw scores into final marks; translating items concerns language adaptation and equivalence across languages.
