- Data Drift
- Carried into education, assessment items drift out of fit as cohorts change, and item-response monitoring, periodic re-calibration, and retiring drifted items are the educational analogue.
This sourceDocuments item parameter drift in item-response theory — assessment items lose fit over testing occasions/cohorts, biasing ability estimates and requiring recalibration or retiring drifted items.
Supported in partVerified against the publisher's abstract
The abstract supports only that item parameter drift exists in IRT and affected ability estimates slightly; it does not mention cohorts, monitoring, re-calibration, or retiring drifted items.
“Results indicated that item parameter drift, under the conditions simulated, had a small effect on ability estimates.”
- Carried into education, assessment items drift out of fit as cohorts change, and item-response monitoring, periodic re-calibration, and retiring drifted items are the educational analogue.
Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
