What does a test plan consist of?

A test plan is fundamentally designed to provide a detailed outline of the content that will be evaluated in a given assessment. This includes the specific topics and concepts that have been taught in class, allowing both instructors and students to understand what material needs to be studied or taught prior to the assessment. By outlining the content, it ensures a systematic approach to evaluating student knowledge while aligning with the curriculum. This fosters a clear understanding for students, making it easier for them to prepare adequately and effectively for their examinations, ultimately leading to a more structured learning environment.

The other options do not encompass the comprehensive aim of a test plan. A random selection of topics may lead to inconsistency and confusion, an informal agreement lacks the necessary structure and documentation for effective assessment, and a specific set of grading criteria tends to focus solely on evaluation metrics rather than on the content that students are expected to learn and demonstrate proficiency in. Therefore, the correct choice accurately reflects the essential function of a test plan in an educational context.
