//MARK
Twelve competencies. Four skills. One honest read.
MARK is the public evaluation standard for product judgment — four skills, twelve competencies, four levels, behavioral anchors at every rung. It is versioned so old results stay interpretable when the standard moves. It is panel-upheld so your mark means the same whether or not the person who wrote it reads your work. Every Brief result footer cites it. Every Practice session accumulates evidence toward it. This page is the entry point — it teaches the spine, routes you to the Skill Scan, and points at the full canon.
Why judgment, specifically. AI made implementation free — it handed implementation-level tasks to anyone with an API key. What that compressed was breadth: writing PRDs, running sprints, coordinating launches. What it made scarcer was the call upstream of all of that — what is worth building, which direction to face, when to kill the thing you shipped six months ago, when to hold the position the room is pressuring you to drop. Judgment is the durable half of product work, and that is what your MARK certifies.
