Advisory Committee


The Advisory Committee invited three experts to serve as consultants to two subcommittees. Consultants participated in subcommittee discussions and decisions. They were not members of the full Advisory Committee, but like Advisory Committee members, consultants completed all necessary training prior to their work on subcommittees. The federal government formally reviewed and cleared all consultants.
