CK-12’s mission is to provide a free platform for teaching and learning. To do so, it is important to minimize legal and compliance costs, and to ensure our tools and content are used for educational purposes only. This will allow us to devote our resources to providing teachers and students the best content and tools possible. We thank you for your interest in and use of the CK-12 Platform, and encourage you to review our updated Terms of Use here and our new CK-12 Curriculum Materials license here. If you have any questions about how our new terms and license may affect your use of CK-12, please let us know.
