Which practices contribute to evaluating reliability and validity of holistic assessments?

• A. Triangulation, expert review, clear scoring rubrics, pilot testing, and alignment to defined constructs.
• B. Rely solely on instructor intuition.
• C. Use a single expert's opinion without testing.
• D. Ignoring alignment to constructs.

Answer: (A)

Establishing reliability and validity in holistic assessments comes from using a combination of evidence and systematic checks that verify what the assessment is supposed to measure and that scores are consistent. Triangulation adds strength by bringing in multiple data sources or perspectives, so the conclusions aren’t dependent on a single viewpoint. Expert review brings informed judgment to ensure the content covers what it should and that items are clear, fair, and aligned with the intended domain. Clear scoring rubrics provide explicit criteria for each performance or response, which helps different raters apply the criteria consistently and reduces ambiguity. Pilot testing lets you try the assessment with a small group to catch confusing items, unseen biases, or scoring issues before wider use, giving you data on reliability and potential validity problems. Finally, alignment to defined constructs ensures every part of the assessment maps to the intended knowledge, skills, or abilities, which supports both content validity and construct validity. Relying solely on instructor intuition lacks evidence you can trust across different learners or contexts, so it doesn’t establish reliability. Relying on a single expert’s opinion without any testing misses the broader scrutiny that helps catch bias or gaps. Ignoring alignment to constructs undermines the very purpose of the assessment, making it hard to claim that the results reflect the intended abilities.
