Again, the curriculum components represent a "buffet" of choices for instructors. Instructors should choose the units within components that are relevant to their course curriculum and that will fit within their particular time constraints (e.g., length of program, online or classroom setting, whether students are full-time or part-time, etc.). The components are designed to be both broad and deep, so there is usually more material available in a component than can be fit into a single course. Experience shows that students can become frustrated with a course that is too fast-paced and jam-packed with material.
