The described scoring of /s/ productions labeled each response as correct or incorrect. This method is known as

• A. Two-way scoring
• B. Standardized scoring
• C. IPA scoring
• D. SODA scoring

Answer: (A)

Binary correctness judgments evaluate each instance of the target sound as either correct or incorrect. When you rate every /s/ production this way, you create a simple accuracy measure (percent correct) and generally higher inter-rater reliability because there’s little room for subjective interpretation. This directly fits the described method of labeling each response as correct or incorrect. It’s different from SODA scoring, which categorizes errors as substitutions, omissions, distortions, or additions; it also differs from standardized scoring, which relies on normative comparisons, and from IPA scoring, which focuses on transcription labels rather than a yes/no judgment of accuracy.
