Knowledge-based Model

In this model, the student has the option of studying a module, or taking a diagnostic exam to measure knowledge in that topic and placing out of the topic. Prior to each topic, a diagnostic exam es taken, and the student can place out of each topic in which minimum grades are achieved. The student does not have to waste time in topics that he already knows. This model is useful for students with different levels of knowledge and experience, it applies more to courses that are less technical, like customer service and sales courses.
