Teachstone

Teachstone develops and delivers tools and support to help educators understand and improve the interactions that shape children’s learning and development. Founded in 2008, the company introduced the Classroom Assessment Scoring System (CLASS) to organizations in the United States and internationally. Its work is grounded in the view that positive, intentional interactions between educators and students contribute to students’ academic and developmental success.

CLASS is an observation tool for measuring the quality of interactions between teachers and children. Teachstone’s website describes multiple versions for different age groups and school stages, including CLASS 2008 for Infant, Toddler, Pre-K, Upper Elementary, and Secondary, and CLASS 2nd Edition for Infant–Toddler and Pre-K–3rd. The tool is intended to help educators and programs focus on meaningful interactions as part of efforts to support learning and development.

The company supports schools and education organizations with observation, training, coaching, and professional development. Teachstone says its services help practitioners understand which interactions matter, strengthen their skills, and assess progress. It also offers training designed to prepare observers to measure educator-child interactions reliably, alongside actionable feedback and educational resources.

Teachstone’s digital offering, myTeachstone, is described as an online subscription service that combines observation data with CLASS resources and professional development. The platform is intended to help organizations implement CLASS. Teachstone also provides user-friendly content and technology to support educators and organizations in applying interaction-focused practices.

The organization works with a range of education partners, including Head Start programs, high schools, and schools associated with military bases. Teachstone describes partnerships with practitioners and researchers: educators contribute classroom experience, while research helps the company study meaningful interactions and refine its support. The company serves education organizations in the United States and around the world.

Teachstone presents its purpose as helping educators use the power of everyday interactions so more students can thrive. Its stated beliefs emphasize the importance of positive relationships from the earliest years, and the potential for students to achieve when supported by teachers who connect effectively with them. The company also identifies itself as a Certified B Corporation and says it works to improve teacher-child interactions within a business community committed to social and environmental impact.

Teachstone is headquartered in Charlottesville, Virginia.
