Accommodations for English Language Learner Students: the Effect of Linguistic Modification of Math Test Item Sets

This study examined the effect of linguistic modification on middle school students’ ability to show what they know and can do on math assessments. To do so, two item sets with 25 multiple-choice items each were developed, one containing original math items and one containing these items with linguistic modifications. Items were selected from two content strands: (1) measurement and (2) number sense and operations. Efforts were made to ensure that both sets of math test items met stringent guidelines for grade and population appropriateness, content rigor, and standardized administration. In developing the two item sets, researchers solicited input from experts and collected data through cognitive interviews and pilot testing.
