This focus on learning outcomes emphasizes that it is the quality of a CAS activity (its contribution to the student’s development) that is of most importance. The guideline for the minimum amount of CAS activity is approximately the equivalent of half a day per school week (three to four hours per week), or approximately 150 hours in total, with a reasonable balance between creativity, action and service. “Hour counting”, however, is not encouraged.
