ACT Invests in Open Assessment Technologies (OAT), the Global Leader for Open Source Assessment Solutions

Strategic Investment Will Expand OAT’s Solutions Portfolio and Advance ACT’s Transformation to a Learning, Measurement and Navigation Organization

SAN FRANCISCO, CA and IOWA CITY, Iowa—ACT, the non-profit learning, measurement and navigation organization known worldwide for education and workforce assessments such as the ACT® test and ACT® WorkKeys®, announced today a strategic investment in Open Assessment Technologies S.A. (OAT), the award-winning provider of open source assessment solutions best known for its QTI®-native assessment platform, TAO®. Financial terms were not disclosed.

ACT’s investment affirms OAT’s leadership in QTI-based assessment solutions and will enable OAT to further scale and diversify its product and service offerings globally. In addition, OAT, as steward of the TAO open source community, will continue to integrate feature contributions by ACT and other leading organizations to the benefit of assessment users worldwide, providing a robust foundation for product interoperability, a key requirement for digital learning and assessment solutions across educational and corporate sectors.

“Both ACT and OAT are committed to delivering enhanced capabilities to customers more efficiently and at a lower cost compared to traditional offerings,” said Marten Roorda, ACT CEO. “The TAO platform reflects ACT’s vision of building innovation in assessment through the power of open source and open standards.”

ACT’s investment aligns with its goal to deliver digital assessments that support education and workforce skills measurement. Currently, ACT uses the TAO platform to deliver ACT WorkKeys, a comprehensive assessment program that aligns, builds and certifies the skills needed for workplace success. Tens of thousands of employers across the US and the world use WorkKeys assessments, and nearly 4.4 million credential certificates have been issued.

“We are pleased to work with ACT as we pursue a shared vision of spearheading and accelerating the adoption of open source solutions and technology standards to make interoperability a reality,” said Marc Oswald, co-founder and CEO of OAT. “The adoption of open source and open standards has become critical, because it enables the disaggregation of content and platform and improves system interoperability to support modern assessment needs and preferences.”

ACT joins European assessment and technology leaders Cito and the Luxembourg Institute of Science and Technology as OAT’s institutional shareholders.

“At OAT we see first-hand the global demand for adaptive learning and assessment solutions that help customers eliminate proprietary data silos and empower them to retake control of their content and data, leading to a reduction in the operating resources needed—both human and financial,” Oswald added.

Since the launch of OAT in 2013, customers around the world have benefitted from having a sophisticated edtech partner who helps them transition to a digital assessment and learning environment.

By capitalizing on TAO’s QTI-native item bank, customers avoid getting their content assets trapped by proprietary data formats. And, by relying on the company’s focus on privacy and information security compliance, they increase the security of student and candidate data when delivering assessments at scale through the TAO Cloud™.

“The world’s leading digital assessment organizations have a very effective collaboration in IMS Global, focused on open standards for highly engaging and innovative assessment of learning,” said Dr. Rob Abel, chief executive of IMS Global. “The investment in OAT by ACT is further evidence of the broadening demand for innovative solutions based on open standards enabling the next generation of digital learning and assessment.”
