What is the process by which candidates can sign up to take the examination?

The correct answer relates to the term commonly used to describe the action of officially signing up to participate in an examination. In the context of standardized tests and certifications, "registration" refers specifically to the formal process where candidates provide their necessary information and pay any applicable fees in order to secure a spot for the upcoming examination. This process ensures that the examining body can prepare adequately for the number of participants and manage any logistical concerns associated with administering the test.

While other terms like "application process," "enrollment," and "assessment booking" might suggest similar concepts, they are typically not used in the context of signing up for examinations. "Application process" usually pertains to the procedure of applying for programs or positions rather than specifically for tests. "Enrollment" typically refers to signing up for courses or classes rather than to take an exam. "Assessment booking" may imply scheduling an assessment but does not capture the formal elements of signing up like registration does. Therefore, "registration" is the most precise term that aligns with the established procedures for candidates preparing to take an examination.
