What type of assessment allows the use of reference materials during examination?

An open book test is specifically designed to allow candidates to bring reference materials, such as textbooks, notes, or other resources, into the examination setting. This format is intended to assess a candidate's ability to apply knowledge and utilize resources effectively rather than simply memorizing information.

In this type of assessment, the focus is on critical thinking, problem-solving, and the application of concepts to practical scenarios, which can often lead to a deeper understanding of the subject matter. The use of reference materials means that candidates can look up information when needed, giving them the opportunity to demonstrate their comprehension and analytical skills instead of solely relying on memorized facts.

In contrast, other assessment types, such as closed book tests, do not permit external materials; take-home exams are generally structured to be completed outside of a regulated environment without real-time supervision; and in-class quizzes usually have time constraints that limit the depth of content covered, with varying rules about resource utilization. Thus, the open book format distinctly encourages a different style of learning and assessment compared to the other options.
