Raising Standards. Promoting Confidence.

At Open Assessment Technologies (OAT), we come to work every day with a vision to deliver advanced assessment solutions that guide teaching and empower learners to succeed. Because we’re serious about the possibilities of digital transformation in the assessment world. 

Today’s eLearning landscape is continuously evolving. Everyone is guessing when it comes to technology—but not us. As the providers of the TAO assessment platform, we’ve worked with both independent organizations along with some of the world’s largest Departments and Ministries of Education for over a decade to pioneer innovative solutions and set the standard for the future of digital learning.
