Each badge has two mandatory requirements for each age level and then a set number of optional requirements to choose from to complete the badge. The number of optional requirements needed is dictated by the age of the person earning it. Of the mandatory requirements, the first is always to complete the mandatory requirements of all lower levels. This is to ensure that a child builds their knowledge from the ground up and does not miss out on any important information. While some of the requirements may be overly simplified due to the fact that they were written with younger children in mind, the knowledge or skill is just as important for the older members and is usually quite simple to complete.
