What is the final step in creating a test instrument?

Establishing the scoring criteria is the final step in creating a test instrument because it provides a framework for evaluating the responses of test-takers. Scoring criteria define how each question will be assessed, whether through rubrics, point values, or specific grading standards. This ensures that the evaluation process is consistent, fair, and aligned with the objectives of the test.

Prior to this step, creating the test questions involves formulating the content to be assessed, which is foundational but is followed by determining how to administer the test, which addresses logistical considerations of delivery. Developing a grading scale relates to how overall student performance will be categorized, but without established scoring criteria, the grading scale lacks the necessary structure for accurate evaluation. Thus, scoring criteria serves as the final underpinning that solidifies the assessment process.
