Building upon decades of international assessment experience, Progressive Achievement for International Schools (PAIS) is designed to provide educators with immediate and relevant feedback to support evidence-based teaching and improve student learning outcomes.

Designed for an international school context

PAIS has been created for international schools and schools with an international focus. Test content is culturally diverse and not aligned to a particular curriculum.

Trusted assessments by a world leader in education

ACER is globally renowned for its work in assessment, educational research and products and services that improve learning across the lifespan. Since it was established in 1930, it has also built a strong reputation as a provider of reliable support and expertise to education policymakers and professional practitioners.

Powered by Progressive Achievement

Progressive Achievement is the idea that all learners can be supported to demonstrate progress, regardless of starting points. It underpins much of ACER’s work, including the PAIS suite.
