The answer is the National Association of Barber Boards of America. Milady's History chapter names the organization directly, referring to "members of the National Association of Barber Boards of America (NABBA)." NABBA is the real national body that connects individual state barber boards — including the TDLR in Texas — around shared licensing standards.
Knowing what NABBA stands for matters beyond the exam itself: it's the same organization behind the multi-state licensing consistency that makes barber license reciprocity between states possible in the first place, a topic covered in FadeJunkie's reciprocity guide.
