Mastery-Based Learning
Mastery-based learning means a learner moves on to the next skill only once they've met a real, defined bar of competence in the current one — not once a fixed amount of time or number of sessions has passed. Progress is measured by what you can actually do, not by how long you've studied.
Definition
It's the opposite of time-based progression ("finish this chapter by Friday regardless of whether it stuck"). A mastery-based system defines criteria for what "done" means for a given skill — a score threshold, a number of correct repetitions, evidence of applying it in a real task — and treats those criteria as the actual finish line, not the calendar.
Why It Matters
Time-based progress creates the illusion of learning: you covered the material, so the box gets checked, whether or not the skill actually stuck. This is exactly why people can "finish" a course and still be unable to do the thing it was supposed to teach. Mastery-based tracking makes that gap visible instead of hiding it behind a completed checklist.
How It Works
A skill or topic gets one or more explicit mastery criteria attached to it — something concrete and checkable, not "understand X well." A learner keeps working the skill (practice, flashcard review, applied tasks) until the criteria are actually met, and only then is it marked mastered. Some approaches also revisit mastered material later (see spaced repetition) to confirm it's staying, not just that it passed once.
Example
Instead of "spent 3 hours on fractions," a mastery criterion might be "solved 10 fraction problems in a row without a mistake" or "applied fraction simplification correctly in a real word problem" — a concrete bar, not a time budget.
Common Mistakes
Setting mastery criteria so vague they can't actually fail ("feel comfortable with X") defeats the whole purpose — if there's no way to fall short, it isn't a real bar. The opposite mistake is setting the bar so high or so narrow that legitimate competence never counts, which turns a useful system into a source of discouragement instead of signal.
How RodionSkill Uses Mastery-Based Learning
Skill Tree nodes in RodionSkill can carry explicit mastery criteria, and a node's status reflects whether those criteria are actually met — not just whether it was opened or worked on — so a Subject's overall progress reflects real competence, and Next Action recommendations prioritize what still needs real mastery, not what's merely been touched.
