Level 4 requires documented business outcomes — financial, operational, or strategic — linked to learning initiatives. There is no formal certification; achievement is determined by evidence.
In practice, many organizations measure only reaction or basic learning, making documented Level 4 outcomes uncommon.
I didn't set out to achieve Level 4. I set out to build a learning function — not just a place to store information, but a system designed to run and be sustained, and to actually change how people worked. The goal was to get everyone moving in the same direction: make the opaque transparent, make the right thing the easiest thing to do, and make sure nothing lived only in someone's head. When I mapped what I'd built against this framework, the evidence was already there.
