The Role of Order and Sequence of Options in Multiple-choice Questions for High-stakes Tests of English Language Proficiency
High-stakes and high-volume English language proficiency tests typically rely on multiple-choice questions (MCQs) to assess reading and listening skills. Due to the Covid-19 pandemic, more institutions are using MCQs via online assessment platforms, which facilitate shuffling the order of options within test items to minimize cheating. There is scant research on the role that order and sequence of options plays in MCQs, so this study examined the results of a paper-based, high-stakes English proficiency test administered in two versions. Each version had identical three-option MCQs but with different ordering of options. The test-takers were chosen to ensure a very similar profile of language ability and level for the groups who took the two versions. The findings indicate that one in four questions exhibited significantly different levels of difficulty and discrimination between the two versions. The study identifies order dominance and sequence priming as two factors that influence the outcomes of MCQs, both of which can accentuate or diminish the power of attraction of the correct and incorrect options. These factors should be carefully considered when designing MCQs in high-stakes language proficiency tests and shuffling of options in either paper-based or computer-based testing.
