Standardised International Large-Scale Assessments (ILSAs) have gained prominence in global and national educational discussions. ILSAs claim to offer valuable insights for improving education systems, but their impact on educational policy varies and has become a contested arena. This article analyses how these assessments fed educational policymaking in six Latin American countries based on a review of policy documents; the article advances three theses on how ILSAs are used by policymakers: First, there is a tokenistic usage of ILSAs; second, ILSAs must be considered more as political devices bolstering national reputation rather than studies in the academic sense; third, ILSAs can serve as leverage tools that can be mobilised for broader political ends. The study shows that the promises, designs and reporting of ILSAs are not necessarily aligned, that participation in ILSAs has become a symbolic gesture, and that ILSAs' data are often cherry-picked to support pre-existing diagnoses and policy agendas.
