Making Assessment Accessible to All

Our mission is to advance online assessment to empower today’s learners and tomorrow’s leaders. So, we make it our priority to provide reliable and accessible online assessment tools — and make them available to everyone through openness and collaboration. TAO Core and the TAO Community make this possible. 

We built TAO Core, our extensible assessment platform edition, specifically for the open source Community, with the goal of providing free, global access to digital test creation software. TAO Core runs on open source and open standards by design to enable maximum freedom, flexibility and control over your test authoring and delivery experience. Available at no cost, TAO has delivered more than 100 million tests, in over 30 languages, worldwide. 

Our Commitment to Open Standards

IMS standards first badgeWe are proud supporters of the IMS Standards First Pledge. As part of a community that is committed to make open standards the first and primary choice for education technology integrations, we are advocates for standards based integrations.

We believe that achieving and promoting official product certification to open standards enables a better EdTech ecosystem and community and believe in fair and open business practices for suppliers.  Find out more about Standards First.
