Merit Badges
The national BSA organization regularly surveys youth members about what topics they would like to see covered by a merit badge. The current list of merit badges is on this page, along with the requirements to earn the respective merit badge:

Merit badges are established and updated when the national BSA organizations assembles national experts on the particular career, academic field, hobby, sport or other topic. Often a national professional association plays this role. With so many girls joining the BSA and its Scouts BSA program, there may be interest in topics especially requested by girls that are not adequately covered by current merit badges. I am sure the BSA would either establish new merit badges or revise/expand the coverage of existing merit badges in response. I looked over the list of the current merit badges and believe there will be strong girl interest in all of the existing ones. And boys will be interested in any new badges as well.
My choice of wording (girl-specific) was poor. I should have said something like girl-requested.
I'm a little beyond the scope of this posting, which is supposed to be about what our own Scouts BSA Troop 248 for Girls will be doing. I am not part of the national organization, can't speak on their behalf and don't want to get into their operations.
