age. The main four, rectangular in shape, were in order of age the Scout Award, the Pathfinder award, the Explorer award and the Chief Scout's Award. These four required the completion of activities from six developmental areas: scoutcraft, adventure, culture, community, health and commitment. Additional optional awards were the Patrol Activity Award, which were team based activities, the Leadership award, which develops leadership within the older Scouts, and the Chief Scout's Challenge, which encourages the application of skills already learnt and includes an expedition. Activity badges Activity badges are awarded for demonstrating skill or achievement in a particular subject which may be an existing hobby or a new area of knowledge. Prior to 2002, these were called Proficiency badges, as Scouts would need to be proficient in the skills and pass a test to prove completion. These came in five groups: interest (based on hobbies and intended for younger Scouts), pursuit (intended for older Scouts and explored a subject in more detail), service (applying theory and practical to teach skills to others), instructor (intended for older Scouts to prove expertise enough to teach younger Scouts) and collective achievement (gained through working in a patrol). In 2002, the current name of activity badges was used to modernise and better describe their purpose. There are currently 59 different badges available with the most recently added being a Scientist badge in March 2019 and the fundraising and geocaching badges in April 2014. Upon their introduction in 2002 there were 70 activity badges however this number has decreased as a number of badges have been replaced by staged activity badges, in particular the three nautical skills badges, the three aviation skills badges as well as other progressive skills through the movement such as snowsports, emergency aid and navigation. The badges are circular in shape and are navy blue with a red border replacing the diamond badges used before 2002 that were green (interest and pursuit), red (service) green and red (collective achievement) or gold bordered (instructor). Staged Activity Badges Staged Activity Badges can be completed by any member of the movement between the age of 6 and 18. They are completed in different stages, so after completing each stage members are awarded the relevant badge and can advance to the next level regardless of their section. Current Staged Activity badges that are available are Air Activities, Community Impact, Digital Citizen, Digital Maker, Emergency Aid,
