Özet
On-demand testing requires that multiple forms of an exam should be administered to students in each testing session. However, the use of multiple forms raises test security concern because of item exposure. One way to limit exposure is using parallel forms construction. Parallel forms are different versions of a test that measure the same content areas and have the same difficulty level but contain different sets of items. The purpose of this study is to describe and demonstrate how parallel forms can be created from a small item bank using the selected-response item type. We present three unique yet plausible test assembly problems. We also provide a solution for each problem using the results from a free, open-source, software add-in for Microsoft Excel called the Opensolver. Implications for test design and item development are discussed.

One way to limit exposure is with parallel forms construction. Parallel forms are different versions of a test that measure the same content areas and have the same difficulty level but contain different sets of items. The purpose of our study is to describe and demonstrate how parallel forms can be created even from small test banks. We present three unique yet plausible test assembly problems.
