The list of of all merit badges and their requirements can be found in the Scouts BSA Requirements book on Scouting.org. This is the BSA’s official repository for the most current requirements and supersedes any requirements included in the published merit badge pamphlets.
If a new edition of a merit badge pamphlet is introduced with updated requirements after the Scouts BSA Requirements book has been released, a Scout who is starting the badge may choose to follow either set of requirements until the end of the year. At the start of the new year, Scouts who are beginning must use only the new requirements.
If a Scout has already started working on a merit badge when a new edition of the pamphlet is introduced, they may continue to use the same pamphlet and fulfill the requirements therein to earn the badge. They need not start over again with the new pamphlet and revised requirements.
