Note: BSA originally published changes to Cub Scout advancement requirements in late November, 2016, in the form of an on-line document listing the original and proposed requirements.
The revised requirements were later published in addendum booklets to be inserted in the Cub Scout Handbooks for each level until they can be revised and republished. The wording shown below, which  appears in the addendum booklets is similar to, but does not exactly match the wording in the original proposal.

Rank advancement is awarded when each Scout has done the following:

1. Be an active member of your Webelos den for three months.
2. Complete each of the five required Adventures. (Specific requirements for these adventures can be found in this (the) addendum.)
   • Cast Iron Chef
   • Duty to God and You
   • First Responder
   • Stronger, Faster, Higher
   • Webelos Walkabout
3. In addition to the five required adventures listed above, complete at least one elective Adventure of your den's or family's choosing (for a total of at least six adventures).
4. With your parent, guardian, or other caring adult complete the exercises in the pamphlet How to Protect Your Children From Child Abuse: A Parent's Guide.
5. Earn the Cyber Chip award for your age. (The Cyber Chip portion of this requirement may be waived by your parent or guardian if you do not have access to the internet.)
