This page describes how to use a multiple choice test to assess student understanding. The assessment tool is one of a series of Classroom Assessment Techniques (CATs) provided by the Field-tested Learning Assessment Guide (FLAG) website. The CATs of FLAG were constructed as a resource for science, technology, engineering and mathematics instructors to emphasize deeper levels of learning and to give instructors valuable feedback during a course. The multiple-choice test is a flexible assessment format that can be used to measure knowledge, skills, abilities, values and thinking skills. This site provides an overview of this assessment technique, including information about how, when and why to use it. The site is also linked to a set of discipline-specific "tools" that can be downloaded for immediate use, as well as supplementary links and sources to further explore this assessment tool.
