What each level asks of you
A verifier marks against these descriptors. Level 1 is free and self-directed; Levels 2 and 3 use credits and a human verifier.
L1
You can lay out a screen using patterns that already exist.
L2
You design a flow end to end, including its empty, loading and error states, and can defend the trade-offs you took.
L3
You design systems of screens where the whole journey holds up, and set the patterns other designers reuse.
What counts as evidence at L2
A designed flow with the states it covers and the reasoning behind its structure.
Evidence has to be work you did. It is attached to the request and read by the verifier — it is never published.
