The requirements for many Merit Badges changed on January 1, 2009. On August 1, 2008, all Merit Badge pamphlets were reprinted with color photographs, diagrams, and covers effective August 1, 2008. The actual text and requirements in most cases did not change from the previous editions.
The requirements for the following Merit Badges have changed:
The Auto Mechanics merit badge was replaced with badge Automotive Maintenance. Architecture and Landscape Architecture Merit Badges were combined into a single book.
All Merit Badge Workbooks are updated.
Boy Scout Requirement Changes Policy
The requirements for rank advancement, Eagle Palms, and merit badges are effective January 1, 2009, through December 31, 2009. The requirements listed in this book [Boy Scout Requirements] are the official requirements of the Boy Scouts of America. However, the requirements on the following pages might not match those in the Boy Scout Handbook and the merit badge pamphlets, because this publication is updated only on an annual basis. These merit badge requirements also appear on the BSA's official Web site (http://www.scouting.org). The requirements posted on the Web site will coincide with this publication and will be updated at the same time, only on an annual basis.
If a Scout has already started working on a merit badge when a new edition for the pamphlet is introduced, he may continue to use the same merit badge pamphlet and fulfill the requirements therein to earn the badge. He need not start all over again with the new pamphlet and possibly revised requirements.
