In order to check if a course is progressively covering useful items, skills and strategies, it is necessary to have lists of useful items to check the course against. This point is taken up in more detail in the section on attainment goals. The most effective way of making sure that the principle of progressive coverage is applied is to make sure that each learning task has a goal which fits with the plan for the course. Before using a new task teachers should decide what the learning goal of the task is.
