The websites for our K-12 Learning Platforms:

  • Provide authorized educational institutions and their district and school administrators and teachers with password-protected access to educational content for use in their curricula;
  • Permit educational institutions to give their students password-protected access and other access to educational content for use in connection with their studies; and
  • Provide general content and informational services to visitors to our sites who are interested in learning more about our K-12 Learning Platforms.



  1. Navigating our Terms. To assist you in understanding our Terms, we have divided these Terms into numbered sections, and provide a set of definitions to allow easy reference to key concepts. See Section 9 (Definitions).
  2. Password Protected Pages and Open Pages. Each website that hosts one of our K-12 Learning Platforms (a "Platform Website") is divided into two areas: (i) a password-protected area that provides Online Educational Content and that is designed to be available only to Platform Users who hold requisite passwords for their use ("Password Protected Pages"); and (ii) an open area, that provides General Information and certain educational content to users without password requirements ("Open Pages").
  3. Relationship with Your School. HMH enters into relationships with Schools and other Educators, whereby HMH agrees to provide their Administrators, Teachers, Students and other associated individuals with access to its Platforms. These Terms address such access.
  4. Use of Our Platforms.
    1. Student Platform Users; School's Registration Responsibilities. Educators select the Students (and, where applicable, the parents or legal guardians) who will have access to the K-12 Learning Platform and the associated School-Designated Educational Content. The School and its Administrators/Teachers are responsible for registering Students. Although our ClassZone Learning Platform allows certain Students to self-register, the School controls which Students are distributed an access code in order to so register.
    2. School-Designated Educational Content. Educators select the Online Educational Content and K-12 Learning Platform features (where applicable) that will be available for their classrooms ("School-Designated Educational Content"). We then provide this School-Designated Educational Content in accordance with these Terms.

    4. Nature of K-12 Learning Platforms; Innovation. We describe the features and functions of our K-12 Learning Platforms in help-screens, via Technical Support, and other materials (collectively, "Documentation"). We seek to provide innovative and useful online learning experiences for Educators and Students. Toward this end, we might choose in our discretion to alter the methods that deliver School-Designated Content ("Content-Delivery Mechanisms"). We may revise our Documentation to describe updates to our Content-Delivery Mechanisms, either before we release the update or within a reasonable time after release.
    5. Use of Passwords. Once registered, you will receive or otherwise have the opportunity to create a user name and password (your "Password"). The Platform Website at issue will guide you as to requirements concerning the needed "strength" of this Password. Your Password gives you access to Password Protected Pages (the extent of this access may be set by your School-assigned role), and to our Online Educational Content. Please keep in mind that we will treat anyone who uses your Password as "you." We will provide this user with all of the rights and privileges that we provide to you, and we will hold you responsible for the activities of a person using your Password. Therefore, we recommend that you maintain your Password in confidence, and that you notify us immediately if you suspect that someone else is using your Password. If you forget your password: (i) Educators should contact Technical Support for assistance in recovering the password, and (ii) Students should contact their Teacher or Administrator for password recovery support.
  5. Technical Support. We offer certain technical support for our K-12 Learning Platforms, to Educators and Students.
