What special feature of IEA assessments helps gauge student attitudes?

The correct answer highlights the use of contextual questionnaires as a key feature of IEA assessments designed to gauge student attitudes. These questionnaires are specifically tailored to gather insights into students' perceptions, engagement, motivation, and learning experiences. By incorporating these measures, the IEA can assess not just the academic performance of students but also their attitudes towards learning, which is crucial for understanding the broader educational context.

This kind of information can be invaluable for educators and policymakers, allowing them to identify factors that may influence student success and to develop strategies that foster a more positive learning environment. Contextual questionnaires thus provide a comprehensive view of the student experience, beyond mere test scores, allowing for a more nuanced analysis of educational outcomes.
