NQC | <strong>Guide</strong> <strong>for</strong> developing assessment toolsgeneral, validity is concerned with the appropriateness of the inferences, use andconsequences that result from the assessment. In simple terms, it is concernedwith the extent to which an assessment decision about a candidate (e.g.competent/not yet competent, a grade and/or a mark), based on the evidence ofper<strong>for</strong>mance by the candidate, is justified. It requires determining conditions thatweaken the truthfulness of the decision, exploring alternative explanations <strong>for</strong> goodor poor per<strong>for</strong>mance, and feeding them back into the assessment process toreduce errors when making inferences about competence. Unlike reliability, validityis not simply a property of the assessment tool. As such, an assessment tooldesigned <strong>for</strong> a particular purpose and target group may not necessarily lead to validinterpretations of per<strong>for</strong>mance and assessment decisions if the tool was used <strong>for</strong> adifferent purpose and/or target group.GUIDE FOR DEVELOPING ASSESSMENT TOOLS PAGE 28
