The pdf version of the Guide to Advancement 2021 was published on the Advancement Resources web page earlier today.
==> Advancement Resources | Boy Scouts of America (scouting.org)
Also forms 11.2.0.0 and 11.2.1.0 have been updated to match the Guide to Advancement .
There have been many changes to the GTA so it would be well worth your time to carefully review the whole document. In particular, sections 4, 7 (totally rewritten), 8, 9, and 10 have important changes in them.
IMPORTANT NOTE: The online version (HTML) is being updated.
