A skill progression framework is a ladder of rungs for each trade, where every rung is defined by what a person is allowed to do without supervision and is passed only by being watched doing it, never by the time spent on the previous rung. The point of the ladder is permission: it tells the community who may be left alone with a dangerous or vital task and who may not.
The ladder of competence that an apprenticeship moves along, what each rung means, and how the rungs are tied to permissions.
A Rung Is A Permission, Not A Reward
It is tempting to read stages such as observer, assistant, practitioner, journeyman and master as ranks of prestige. They are better read as lists of what the community lets the person do alone. An observer is not left with a tool. An assistant may do simple tasks while watched. A practitioner may do standard work with decreasing supervision. A journeyman may handle unusual problems and teach. A master may take apprentices and sit on the panel that tests others.
That reading makes the framework a safety instrument. For a trade such as running a pressure vessel, the question that matters is: who is allowed to run it without a master standing beside them? If the answer is written down and tied to a test, the community knows. If it is left to feeling, the first time a half-trained operator is alone with a hazard is the first time anyone finds out.
Three Ladders Exist In The Corpus
The corpus uses several ladders, which should not be confused:
- Training stages for the apprenticeship itself: observer, assistant, practitioner, journeyman, master (Duration & Stages).
- Certification levels from the Competency Testing article: Level 1 basic competency, Level 2 journeyman competency and Level 3 master competency, with Level 1 typically reached at the end of a standard apprenticeship.
- Skill-development models such as the one in the node title, novice to master (Novice → Competent → Proficient → Master).
This tree uses the stages for training and the certification levels for permission to practise, and it keeps them separate. A person can be at a late stage of training without yet holding a level.
What You Need
- A written ladder for each trade, with what each rung may do alone.
- Observable milestones (Milestone Definitions).
- Assessors who are not the apprentice’s own teacher (Assessment Methods).
- A final demonstration for master level (Mastery Demonstration).
- A registry that records who holds which level and when it was tested.
Method: Building A Ladder For One Trade
Step 1: List what the trade lets a person do from the simplest task to the most dangerous.
Step 2: Mark the hazardous tasks. These are where permission must be strictest.
Step 3: Group tasks into rungs, putting the hazardous ones high.
Step 4: Write each rung as a permission: “may do X unsupervised.”
Step 5: Attach a test to each rung that can be watched.
Step 6: Record and review. Skills fade, so levels for high-stakes roles need retesting, which the Competency Testing article puts at every five years or after a serious incident.
Common Mistakes
- Defining rungs by time. A year passing is not a competence.
- Defining rungs by knowledge. The test is doing, not talking.
- Leaving the hazardous tasks undefined. They are the ones the framework exists for.
- Mixing stages and levels.

- Combine with: Milestone Definitions — turning each rung into a test
