The Book of Knowledge
The first comprehensive, industry-specific framework written exclusively for professional grill service.

Every established profession has a shared foundation. For the grill service industry, that foundation did not exist. So AGSI wrote it.
The Certification Standards & Competency Framework (BoK) establishes a shared vocabulary, clear boundaries of scope, and defined competency domains grounded in real-world practice.
This document is not adapted from other trades. It was developed specifically for this industry by professionals who understand the work.
