Eagle Extension

National’s FAQ:
Q: Does the National Council grant extensions of time to complete rank requirements beyond the 18thbirthday for the Eagle or 21st birthday for Summit or Quartermaster?
Yes, but only for the Eagle Scout rank as described in GTA Topic 9.0.4.0 or for Venturing Summit or Sea Scout Quartermaster as described in GTA Topic 4.3.3.0. Unit leadership must become familiar with the five tests under 9.0.4.0. The tests were designed to accommodate such obstacles as those presented by COVID-19 disruptions.
Q: Will youth who are not yet Life Scouts be allowed to apply for an extension to earn the Eagle Scout rank?
Extensions are considered only for Scouts who are Life rank. If, once a Scout achieves Life rank, it turns out that COVID-19 disruptions along the way have left them with insufficient time to complete Eagle requirements, then this may be cited when the time comes to submit an extension request.
Q: May local councils grant extensions?
Normally, that is not allowed. However, due to the current situation—effective immediately and through September 30, 2020—council Scout executives may grant extensions, or delegate authority to the Council Advancement Committee to grant extensions under the following limitations:

1. It can be established that COVID-19 disruptions were the only circumstances that delayed work on Eagle Scout/Summit/Quartermaster advancement requirements, such as the service project or merit badges. If any other causes were involved, the extension request must go to the National Council following the process outlined in the GTA.
2. Extensions shall only be granted to youth in Scouts BSA who have already achieved Life rank. . . .”

The answer is yes.  Council has limited authority to grant the request.  National retains the authority outside that scope. The process is the same.
