What type of examination focuses on the content of a specific chapter?

The type of examination that focuses specifically on the content of a single chapter is the chapter exam. This type of assessment is designed to evaluate a student's understanding and retention of the material covered within that particular chapter. It typically includes questions that directly relate to the concepts, terms, and key points presented in the chapter, allowing for a targeted assessment of the student's grasp of the subject matter.

In contrast, a final exam covers all the material learned throughout the course, often encompassing multiple chapters, and is generally comprehensive in nature. A midterm exam also assesses a wider range of content, typically spanning the first half of a course, rather than being limited to just one chapter. A diagnostic exam is used primarily to identify a student's existing knowledge and skill levels before beginning a new course or unit, rather than to evaluate understanding of chapter-specific content.
