If the requirements for a merit badge on the required list for the Eagle Scout rank vary among the Boy Scout Handbook, the merit badge pamphlet, and the Boy Scout Requirements book (current edition), which resource takes precedence?

The current edition of the Boy Scout Requirements book lists the official set of requirements for rank advancement and for each individual merit badge.

However, updated merit badge requirements will sometimes be made available at Scouting.org/meritbadges before the Boy Scout Requirements book is published.

Scouts may use, or switch to, these updated requirements.
