Establish the goal
Define the capability, decision, performance, or body of work the learner is trying to produce.
The Pristone System
The Pristone Method
A shared operating method for turning a broad goal into observable capability: diagnose real performance, isolate the constraint, build deliberately, test transfer, measure the change, and update the plan.

The Pristone Method
One capability loop across every track.
- Diagnose
- Prioritize
- Build
- Test transfer
- Measure
- Re-prioritize
The Pristone Method is not a fixed curriculum. It is an evidence-led loop used to decide what a learner needs now, how to work on it, and what evidence should change before the plan moves forward.
Written and operationally reviewed by Edward Mabonga, founder of Pristone Academy.
The capability loop
Eight decisions, repeated as the learner changes
The method stays consistent across subject areas while the evidence, exercises, and performance criteria change.
Diagnose
Observe real performance rather than inferring the problem from a score, title, or self-description alone.
Decompose
Separate knowledge, recognition, strategy, execution, interpretation, pacing, judgment, and communication.
Prioritize
Choose the smallest number of constraints that will create the greatest useful change.
Build capability
Combine direct instruction, deliberate practice, project work, feedback, and independent application.
Test transfer
Use an unfamiliar problem to check whether the learner can perform without reproducing a memorized solution.
Measure
Compare new evidence with the baseline using the dimensions that matter for the learner's actual goal.
Re-prioritize
Update the plan as the learner improves, because the highest-leverage constraint should change over time.
Diagnostic language
Different errors require different interventions
More practice is not a diagnosis. Pristone separates the type of breakdown before deciding what to teach or rehearse.
Conceptual
The necessary idea or fact is not yet understood.
Recognition
The learner knows the concept but does not recognize when it applies.
Strategic
The chosen approach is inefficient, fragile, or poorly matched to the problem.
Execution
The plan is sound, but the implementation, calculation, or procedure breaks down.
Interpretation
The learner misreads the task, evidence, constraint, or requested output.
Pacing
Time or attention is allocated in a way that prevents a complete performance.
Judgment
Tradeoffs are noticed but not weighed appropriately for the situation.
Communication
The reasoning is stronger than the learner's ability to make it clear and defensible.
This taxonomy is a working diagnostic vocabulary, not a clinical or psychometric assessment. It organizes observable learning and performance behavior.
Transfer
The goal is independent performance, not assisted completion
A new problem
The learner applies the capability to work that is similar enough to be relevant but different enough to prevent memorized reproduction.
A clear explanation
The learner makes assumptions, decisions, and tradeoffs visible instead of only presenting a final answer.
Reduced support
Prompts and scaffolding are deliberately withdrawn so independence can be observed rather than assumed.
Continue through the Pristone system
Start with evidence, not assumptions.
A paid diagnostic applies the method to your actual goal and produces a written priority plan. There is no commitment beyond the first session.
