What is the term that refers to the accuracy of an assessment?

The term that refers to the accuracy of an assessment is validity. Validity is concerned with whether an assessment measures what it is intended to measure. For example, if a test is designed to assess a student's understanding of mathematical concepts, it should accurately reflect their knowledge in that area rather than testing unrelated skills.

This concept is crucial in educational leadership and assessment design because it ensures that results are meaningful and can be used to make informed decisions regarding instruction and student learning outcomes. If an assessment lacks validity, the conclusions drawn from its results may be misleading, impacting educational strategies and student support.

While reliability refers to the consistency of assessment results over time or across different raters, and feasibility pertains to the practicality of implementing an assessment, such as time and resources required, these terms do not address the accuracy of the assessment itself in measuring intended outcomes. Effectiveness generally relates to the impact of an intervention or program rather than the accuracy of a specific assessment.
