Sound screening tools are:

Sound screening tools are:

• A. Reliable, valid, and free of bias
• B. Reliable but biased
• C. Invalid and biased
• D. Unreliable

Answer: (A)

Sound screening tools should be reliable, valid, and free of bias. Reliability means they give consistent results across different occasions, raters, or versions, so a child’s screening outcome won’t swing unpredictably. Validity means the tool actually measures what it’s intended to measure, accurately flagging children who need further assessment rather than producing random or unrelated results. Being free of bias ensures the tool works fairly across diverse backgrounds, so language, culture, or socioeconomic factors don’t cause unfair misclassification. If a tool is reliable but biased, it would yield consistent yet unfair results for some groups. If it’s invalid, it won’t measure the intended construct at all. If it’s unreliable, its results would vary each time, making decisions inconsistent and untrustworthy.
