What is the extent to which language conforms to the rules of the standard variety?

• A. Accuracy
• B. Fluency
• C. Complexity
• D. Register

Answer: (A)

Accuracy measures how closely language follows the rules of the standard variety, including grammar, word forms, spelling, and punctuation. In assessment terms, it reflects how often the language adheres to conventional norms and where errors occur. This is why it’s the best choice here: it directly captures conformity to standard rules, unlike fluency (smoothness and speed of speech), complexity (range and sophistication of structures), or register (appropriateness to context). For example, using the correct past tense form, proper subject–verb agreement, and accurate punctuation demonstrates high accuracy. Even if someone speaks quickly and fluidly, frequent grammatical mistakes reduce accuracy, illustrating why accuracy specifically targets conformity to standard rules.
