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 specifically for the open source community, with the goal of providing free, global access to digital assessment solutions. Available at no cost, 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.

With an Open Source platform like TAO, we are free to do our own customization, because we can control the source code. This came as a huge relief, since proprietary systems are very restraining. The more a proprietary system was customized the more we would be dependent on it. Thankfully, with TAO we found a solution that is open and flexible for the future. It is a big step in the right direction to ensure consistent, nationwide implementation of our learning standards.
