What term describes the positive or negative impact of a test on classroom teaching?

• A. Backwash
• B. Feedback
• C. Assessment impact
• D. Curricular influence

Answer: (A)

Backwash describes the effect a test has on how teachers plan and carry out classroom instruction. When assessments align with learning goals and provide clear criteria, teaching tends to reflect those goals, use similar tasks, and offer feedback that helps students improve, which is positive washback. Conversely, if an assessment emphasizes only certain formats or content, instruction can narrow to those areas and become aimed at test performance rather than deeper understanding, which is negative washback. Other terms like feedback focus on information given to students to improve performance, not the broader way teaching responds to an assessment, and curricular influence or general assessment impact don’t pinpoint the specific testing-to-teaching dynamic. So the described phenomenon is backwash.
