PISA 2025: Delivering Secure Digital Assessment at Global Scale with TAO

 

The OECD Programme for International Student Assessment (PISA) is one of the world's most influential international education studies, requiring secure, reliable, and comparable assessment delivery across diverse languages, infrastructures and testing environments.

For PISA 2025, working alongside the Australian Council for Educational Research (ACER) and consortium partners, TAO supported the delivery of more than 900,000 assessment sessions across 91 countries and economies in 54 languages, while enabling both online and offline assessment delivery through a single integrated platform.

The project required a unique combination of scalability, flexibility, reliability and assessment expertise to support consistent delivery at global scale.

The result was an award-winning implementation that established a new benchmark for large-scale digital assessment delivery and demonstrated how modern assessment technology can support complex international programmes without compromising quality, security, or performance.

Deliver the 21st-Century Testing Experience Students & Educators Deserve


Modern curriculums require educators to assess students’ career readiness by measuring 21st Century Skills, which include deeper learning competencies such as critical thinking, collaboration, communication, creativity, and problem-solving. However, these competencies have traditionally been difficult to measure through traditional assessment methods.

By deploying digital assessments with TAO that include interactive items built using Portable Custom Interactions (PCIs), it is possible to open the window to more creative and immersive testing experiences that reveal a student’s thought process throughout problem-solving. For more traditional assessments, TAO supports 17 built-in QTI-based Technology Enhanced Items (TEIs), including multiple-choice, file upload, associate interactions, and more.

TAO's standards-based framework eliminates proprietary data silos and ensures that your content, tests, and assets are 100% interoperable, so you can have complete ownership of the assessment solution and build your program with peace of mind.
