Proxy reporting is a common practice during survey data collection to increase response rates while reducing fieldwork costs, and agreement between proxies and self-reports is critical to make reliable and valid inferences. This study is the first to unpack what influences proxy accuracy in a non-Western setting using data from the 2012 Qatar Education Study. We find that agreement is a function of a student's grade in school, grades, a parent's level of education, and the interaction between immigration status and parent education. These findings suggest in multicultural contexts, agreement may vary based on factors beyond what is typically accounted when examining the components of reporting error as a result of using proxies over self-reports.
