Progress verdict cadence and 3-level outcome model

DEC-0015 - Progress verdict cadence and 3-level outcome model

Context

Need a simple learner-facing outcome model that is stable enough to guide behavior, but still responsive to short-term changes.

Decision

Verdict cadence:

• Weekly tracking is used as progress pulse.
• Monthly cadence is used as official outcome verdict.

Learner-facing outcome levels:

• Can co gang
• Dang on
• Dang tien bo tot

Evaluation logic for learners with goal:

• Use current progress trend + distance to selected goal.
• Monthly verdict is not based on one attempt only.
• If learner has clear positive trend toward goal, verdict can be “Dang tien bo tot” even before fully reaching goal.

Evaluation logic for learners without goal:

• Do not compare against target score.
• Use score trend + diligence together.
• Completed-count only is not enough for verdicting.

Interpretation guardrail:

• Keep verdict language motivational and clear.
• Avoid harsh success/fail wording.

Rationale

Weekly pulse keeps momentum, while monthly verdict reduces noise. Three levels are easy to understand and action-oriented. Trend + diligence avoids misleading verdicts from volume-only behavior.
