Description: Omission rates in large-scale assessment data can threaten the reliability and validity of the reported student scores. A number of studies have examined examinees' omission rates on high-stakes assessments, but few have examined omission rates on low-stakes assessments. In addition, many studies have focused on multiple-choice items, but few have included constructed-response items. This study extends previous research to examine the omission patterns on a low-stakes large-scale assessment that includes both multiple-choice and constructed-response items. Omission rates in relation to item format and student demographics are compared while controlling for ability level. The results showed that omission rates were related to the item formats and subgroup membership of examinees.
