"A test with repeated items is as valid, if not more so, than a test with no anchor items".
Officials said it was standard procedure to repeat certain questions, so-called "anchor items," as a way of aiding year-to-year comparisons.
Museum tack putty is also a good way to anchor items.
These items, therefore, were not suitable to be used as anchor items.
Anchor items assessed the four reading comprehension levels and were invariant across adjacent test forms.
Further, necessary conditions for score-scale comparability include a set of equivalent anchor items.
Only the unique and anchor items selected in the previous phases were considered in this calibration.
As such, our design, even at the extreme, includes a set of non-invariant as well as invariant "anchor" items.
Each of the final test forms of the TRC-e included 33 items, eight of which were anchor items.
In the initial stage, a pilot test was administered to adopt anchor items that could link several test forms.
The values of the common items, also known as anchor items, are crucial to align the metrics from different test forms, in order to compare scores.
