TAO® is the only open source, QTI-native item authoring, item banking, and test assembly system available in the EdTech industry, recognized across the globe as the leading assessment platform for education, career, and industry advancement.
With over 100 million test deliveries in more than 30 languages worldwide, TAO is designed to support the end-to-end assessment cycle through feature-rich modules for test authoring, rostering, delivery and reporting. The solution can be deployed as-is, modified with new features, and integrated with other tools and administrative systems. Thanks to this modular design principle, TAO users can assemble the functionality they require, and/or build on top of a large set of pre-existing features and functionalities.
Unique in the assessment marketplace, OAT also publishes the TAO software under an open license, which guarantees free access to the source code and eliminates expensive software license fees and lock-in to proprietary products. Testing agencies can deploy a system of their own that is based on open TAO components while benefiting from the flexibility to integrate customizations and innovations that meet their needs on their timeline.
