Two types of prerequisites are configurable in Webassessor™.

Account based prerequisites link the test taker's data to their eligibility to take an exam. For example, a test taker may only be allowed to take a test if they have a certain level of education.

Test based prerequisites link the ability of a test taker to register for a test after having already passed prerequisite test or tests. For example, this allows tracks to be set up where a basic exam might be followed by an intermediate and then an advanced level exam.
