As sole IP holders and publishers of CLASS, Teachstone is now poised to innovate around the CLASS, maximizing its reach and impact to programs who are focused on implementing CLASS at scale. "This is big news for us," said Rebecca Berlin, chief strategy officer and interim CEO of Teachstone. "With the IP, we can explore how to make CLASS offerings easier for programs to implement at scale." Originally developed in 2008 by Robert Pianta, Bridget Hamre, and Karen la Paro, the CLASS is used by programs nationwide to assess teaching quality and drive professional development experiences. As part of today's announcement, CLASS products previously published and distributed by Brookes Publishing, LTD, will now be published by Teachstone and exclusively distributed by Kaplan Early Learning. "We would not have made it this far without Brookes Publishing," said Bob Pianta, CLASS author and Teachstone co-founder. "They helped us take the CLASS from research labs at the University of Virginia into classrooms and child-care centers across the country and around the globe. We look forward to building on those accomplishments and continuing to impact teachers and their students with Kaplan Early Learning." Customers can continue to purchase CLASS products through the Teachstone store or through Kaplan Early Learning. ## Subscribe to our Blog Receive timely updates delivered straight to your inbox. - [About Teachstone](http://teachstone.com/about-teachstone/) - [Our Partners](http://teachstone.com/our-partners/) - [Careers](http://teachstone.com/careers/) - [Support](https://teachstone.com/support/) - [Contact Sales](https://info.teachstone.com/contact-a-teachstone-representative) - [Interact Class Summit 2023](https://teachstone.com/interact-class-summit/) Everyday we work to improve teacher-child interactions and we are proud to do so in a business community committed to the highest standards of social and environmental impact.
