Here are some answers for common questions about holding merit badge classes virtually.  From Scouting.org COVID-29 FAQ.

Q: Can merit badge counseling be done using digital technologies like Zoom or WebEx?

Yes, registered merit badge counselors may work with youth using digital platforms, ensuring that all youth protection measures noted in the Guide to Safe Scouting and BSA’s social media guidelines are in place. In addition to youth protection, the advancement guidelines in Guide to Advancement (GTA) Section 7 are required.

Q: Are merit badge counselors allowed to provide online instruction?
Yes. Merit badge counselors should follow the guidelines in the Guide to Advancement 7.0.3.2 and ensure you are adhering to all youth protection requirements and online communications guidelines. It is acceptable—and sometimes preferable—for merit badges to be taught in group settings, including online instruction. We currently allow group instruction at camp and merit badge midways, fairs, clinics, or similar events. These can be efficient methods, and interactive group discussions can support learning. Gathering a group online can also be beneficial. Guest experts and speakers that assist registered and approved counselors may be more willing to speak to a larger online audience. Slide shows, skits, demonstrations, panels, and various other techniques can also be employed, but as any teacher can attest, not everyone will learn all the material. Therefore, the standards we use to verify that each Scout has fulfilled requirements must not be relaxed. Merit badge counselors must be sure that each Scout has individually gained the knowledge intended. When accomplished, counselors can easily sign off requirements via Scoutbook.

Q: Can I connect directly with my Scouts/Venturers/Sea Scouts if I am a merit badge counselor?
Yes. In Scoutbook, merit badge counselors can now connect directly with the Scouts they are counseling; see https://discussions.scouting.org/t/march-23-2020-scoutbook-updates/165970 NOTE: Scouts/Venturers/Sea Scouts still must get approval from their leader, according to Guide to Advancement 7.0.3.0.

Q: How will I know if a Scout/Venturer/Sea Scout has obtained approval from their leader to work on a merit badge?
In the member profile, you will see if the leader has signed off with their approval.
