Your post implies that NCEES is an independent academic organization, with no connection to the state boards. You might want to take another look.
In fact, NCEES is "a national non-profit organization composed of engineering and surveying licensing boards representing all states and U.S. territories." NCEES is administered by state board representatives. NCEES policies are determined by votes of state board representatives. The engineers in NCEES generally have many years of experience in industry and on state boards.
For example, the current
NCEES president is a PE/SE who also serves on the Illlinois Structural Engineering Board, has more than 40 years of consulting experience, and led the investigation of the World Trade Center collapse. The
NCEES president-elect, who takes office next year, is an Electrical PE who serves on the Florida Board for Professional Engineers, and who has 50 years of experience.
NCEES has no particular academic connections, and is not "a group of profs". Perhaps you are confusing NCEES with ABET, the organization that accredits college engineering degree programs.
