Bridging the educational research-teaching practice gap: Tools for evaluating the quality of assessment instruments.

Student assessment is central to the educational process and can be used for multiple purposes including, to promote student learning, to grade student performance and to evaluate the educational quality of qualifications. It is, therefore, of utmost importance that assessment instruments are of a high quality. In this article, we present various tools that instructors could use, both to improve instrument design and validity before presentation to students and, to evaluate the reliability and quality of the assessment after students have answered the questions. In keeping with our goals of the Bridging-the-Gap series, we also present various ideas from the educational literature regarding the evaluation of assessment quality and end with a list of criteria that instructors could use to guide their evaluation process.
