duo-efficacy-measurement

Prove your product actually works — with instruments you did not author, on axes that do not substitute for each other, and in a way a skeptic outside your company can check. Covers the four-axis efficacy framework (enjoyment, mastery, real-task application, external standard), borrowing the incumbent's benchmark instead of inventing a metric, authoring an item pool independently of the content you ship, thin-sampling many users to grade your content rather than your users, embedding a pre-test and post-test as a gate, adaptive assessment, partial-credit scoring, and reading calibration off the score distribution. Use when asking how do I show this actually teaches anything, what do I measure besides engagement, should I build my own test or borrow one, how many questions do I need, where does a pre-test go, why is my assessment too easy, or should I report one score.
