Define the inference the MTTC actually defends

The advice. “OEE should try to find a substantive statement vs. a procedural one” to answer three questions: What can you infer when a student doesn’t get a cut-score? What does performance mean? Scores on the MTTC represent what?

Why. Asked what inferences can be defended for each test, OEE’s answer was that a candidate passing at the minimum cut score can be certificated, which allows a district to interview them. That describes what the score permits, not what it means. It is a description of process, and it cannot be defended in the way a validity claim is defended.

This is the most consequential recommendation of Session 4 because everything else depends on it. “Meaningfully different” has no criterion until the inference is defined — two forms are meaningfully different if they support the same inference equally well, and an undefined inference cannot adjudicate one overlap ceiling against another. The same gap governs MTTC Constructed-Response Endorsements: OEE cannot decide whether a constructed-response endorsement test is necessary without knowing what claim it would support.

Status. Open. No answer offered in the session.
