IRT Observed-Score Kernel Equating with the R Package kequate

The R package kequate enables observed-score equating using the kernel method of test equating. We present the recent developments of kequate, which provide additional support for item-response theory observed score equating using 2-PL and 3-PL models in the equivalent groups design and non-equivalent groups with anchor test design using chain equating. The implementation also allows for local ...

A comparison of Van der Linden's conditional equipercentile equating method with other equating methods under the random groups design

To ensure test security and fairness, alternative forms of the same test are administered in practice. However, alternative forms of the same test generally do not have the same test difficulty level, even though alternative test forms are designed to be as parallel as possible. Equating adjusts for differences in difficulties among forms of the test. Six traditional equating methods are consid...

Sampling of Common Items: an Unrecognized Source of Error in Test Equating1

There is variability in the estimation of an equating transformation because commonitem parameters are obtained from responses of samples of examinees. The most commonly used standard error of equating quantifies this source of sampling error, which decreases as the sample size of examinees used to derive the transformation increases. In a similar way of reasoning, the common items that are emb...
