184.108.40.206 What to Do When Requirements Change
(p. 49 of 2021 Guide to Advancement)
Merit badge requirements, along with changes to them, can be found at the Scouting.org Merit Badges web page: www.scouting.org/programs/scouts-bsa/advancement-and-awards/merit-badges/ Once new or revised requirements appears on that page, any Scout beginning work on a merit badge must use the requirement as stated there.
Changes may also be introduced in a revised merit badge pamphlet, youth handbook, or other official BSA
publication or release before appearing on the Merit Badges web page. In this case, unless official communications set forth a different procedure or establish a date by when use of the old requirements must cease, youth members have through December 31 of that year to
decide what to do. They may continue—or begin work—using the old requirements, or they may switch to—or begin work—using the new requirements. Scouts who choose to use the old requirements may continue using them until the merit badge is completed. Scouts who have not begun work on a badge by December 31 of the year a change in its requirements is announced must use the new requirements.
There is no time limit between starting and completing a badge, although a counselor may determine so much time has passed since any effort took place that the new requirements must be used.
