The Proficiency Scale
A competency is meaningless without a scale to measure it on. "Good at strategy" is a vibe. "On Track on Strategic Impact, with a clear gap on strategy definition" is a coaching plan. This note is the Rosetta Stone for the whole domain: the two scales I use, what each level actually means, and how they line up.
#My point of view: the scale is where most assessment quietly fails
People obsess over the competency list and then bolt on a sloppy scale, the "1 to 5, you know, use your judgment" kind. That is where calibration dies. If two managers do not mean the same thing by a "3," your numbers are noise dressed as data. I would rather have a crude four-competency model with a razor-sharp scale than a beautiful twelve-competency one rated on vibes.
#Scale 1: the 0-2 matrix rubric (the system of record)
The Master Competency Matrix uses a deliberately coarse three-tier scale. Coarse is a feature, because it resists false precision and forces a real call.
| Score | Label | What it means |
|---|---|---|
| 0-0.5 | Needs Focus | Below the bar for the level. A real, named gap to coach against, not a verdict on the person. |
| 1-1.5 | On Track | Meeting the bar for the current level. The healthy default, where most scores live. |
| 2+ | Outperform | Exceeding the level, consistently operating like the level above. This is your promotion signal. |
The genius of three tiers is that "On Track" is the honest center of gravity. A team where everyone is Outperforming everything either has a once-in-a-decade roster or, far more likely, a grading problem.
#Scale 2: the 1-5 mastery scale (the lighter tools)
The 9-skill Eval Sandbox and my score-gated system use a finer five-point scale built on a progression of independence:
| Score | Label | The real test |
|---|---|---|
| 1 | Inadequate (Gap) | Can't do it yet, even supervised. |
| 2 | Supervised (Knows) | Does it correctly with oversight. |
| 3 | Unsupervised (Does) | Does it reliably on their own. |
| 4 | Generates (Masters) | Sets the standard; others learn from how they do it. |
| 5 | Leads (Teaches) | Defines the practice and grows it in others. |
That four-word ladder is the most portable idea in this domain. Can you do it watched, alone, better than others, or teach it? It maps almost one-to-one onto The Six Stages of Mastery, from Gaining Experience up to Recognized Thought Leader, and gives you a fast gut-check on any skill in seconds.
#How the scales line up
The two scales measure the same reality at different resolutions. Here is the crosswalk I keep in my head:
| 0-2 matrix | 1-5 mastery | Mastery stage |
|---|---|---|
| Needs Focus (0-0.5) | 1-2 / Knows | Gaining Experience |
| On Track (1-1.5) | 3 / Does | Applies Practical Knowledge |
| Outperform (2+) | 4-5 / Masters to Teaches | Advanced, then SME and beyond |
No. The target depends on the level. An APM who "Knows" a skill under supervision is exactly where they should be, and pushing them to "Teaches" is malpractice, not ambition. Per-level targets (for example the Eval Sandbox totals APM 14 / PM 22 / SPM 30 / LPM 38 out of 45) exist precisely so "good" is defined for your level, not in the abstract. See Score-Gated Leveling and What Changes at Each Level.
The 0-2 rubric is right for a rich behavioral matrix where nuance lives in the behaviors, not the number. The 1-5 scale is right for a self-assessment radar or a summed leveling score where you need range. Forcing one scale onto both jobs is how you get either false precision or false coarseness.
